Question 1General Intelligence and Reasoning

In a reasoning test for paramedical staff, the statement 'All bandages are sterile items' and 'Some sterile items are cotton rolls' is given. Which conclusion follows necessarily?

  1. All sterile items are bandages
  2. Some bandages may be cotton rolls Correct answer.
  3. No bandage is a cotton roll
  4. All cotton rolls are bandages

Explanation

When one premise is particular ('some sterile items are cotton rolls'), any conclusion linking bandages to cotton rolls can only be particular and possible, never universal. Since bandages fall inside the sterile-items set, it remains possible that some bandages overlap with cotton rolls, so the possibility statement follows. Universal claims about all cotton rolls or all sterile items go beyond what the premises guarantee.

Question 2General Intelligence and Reasoning

A ward register records: Nurse A works on Monday, Wednesday and Friday; Nurse B on Tuesday, Thursday and Saturday; Nurse C on Monday, Thursday and Sunday. Which day has exactly two nurses on duty?

  1. Tuesday
  2. Monday Correct answer.
  3. Saturday
  4. Friday

Explanation

List each day's staffing: Monday has A and C, Tuesday has B, Wednesday has A, Thursday has B and C, Friday has A, Saturday has B, Sunday has C. Only Monday and Thursday show two nurses, and among the options only Monday appears. Thursday is absent from the choices, so Monday is the unique answer.

Question 3General Intelligence and Reasoning

If 'BP' stands for blood pressure, 'HR' for heart rate and 'RR' for respiratory rate, which coded string represents the sequence BP followed by HR followed by RR?

  1. HRBPRR
  2. RRHRBP
  3. BPHRRR Correct answer.
  4. RRBPHR

Explanation

The sequence is given in order: BP first, then HR, then RR, so concatenating the codes gives BPHRRR. Reading order must be preserved exactly as stated. Any rearrangement of the three codes changes the intended sequence.

Question 4General Intelligence and Reasoning

A paramedical reasoning paper codes 'dressing' as 'efttjojoh' using a simple letter shift. Using the same rule, how would 'suture' be coded?

  1. tvtsue
  2. tuvsfe
  3. tvuvsf Correct answer.
  4. rtutse

Explanation

Comparing dressing with efttjojoh shows each letter moved forward by one position in the alphabet (d to e, r to s, and so on). Applying the same forward shift to suture gives s to t, u to v, t to u, u to v, r to s, e to f, producing tvuvsf. The rule must be applied uniformly to every letter.

Question 5General Intelligence and Reasoning

In a hospital seating arrangement, five patients P, Q, R, S and T sit in a row facing north. Q is immediately right of P, R is at the extreme left, and T is at the extreme right. If S sits between Q and T, who occupies the middle seat?

  1. R
  2. Q Correct answer.
  3. S
  4. P

Explanation

With R at the left end and T at the right end, the row is R, _, _, _, T. Since Q is immediately right of P, the pair PQ fills two adjacent seats, and S sits between Q and T. The only arrangement satisfying all conditions is R, P, Q, S, T, placing Q in the middle seat.

Question 6General Intelligence and Reasoning

A thermometer reading falls from 39.2 to 38.6, then rises to 39.0, then falls to 38.4. What is the net change from the first reading to the last?

  1. A fall of 0.6
  2. A fall of 0.8 Correct answer.
  3. A rise of 0.8
  4. A fall of 1.0

Explanation

The net change compares only the first and last values: 38.4 minus 39.2 equals minus 0.8, meaning a fall of 0.8 degrees. Intermediate rises and falls do not affect the net figure. Adding the intermediate movements would answer a different question about total variation.

Question 7General Intelligence and Reasoning

Find the next term in the series built on a clinical pattern: 3, 6, 12, 24, 48, ?

  1. 60
  2. 84
  3. 96 Correct answer.
  4. 72

Explanation

Each term is double the previous term: 3 doubled is 6, 6 doubled is 12, and so on. Doubling 48 gives 96, which continues the geometric pattern. Adding a constant would fail to fit the earlier transitions.

Question 8General Intelligence and Reasoning

A blood-sample rack holds test tubes numbered 1 to 40. Tubes with numbers divisible by 3 are sent for glucose testing. How many tubes go for glucose testing?

  1. 13 Correct answer.
  2. 15
  3. 14
  4. 12

Explanation

Multiples of 3 up to 40 are 3, 6, 9 and so on up to 39. Dividing 40 by 3 gives 13 complete multiples with remainder 1, so 13 tubes qualify. Counting the endpoints wrongly is the usual source of error here.

Question 9General Intelligence and Reasoning

In a certain code, 'ward' is written as 'xbsd' and 'care' as 'dbsf'. Using the same rule, how is 'dose' written?

  1. epfs
  2. eqtf
  3. eptf Correct answer.
  4. fpte

Explanation

Each letter of the word is replaced by the next letter in the alphabet: w to x, a to b, r to s, d to e, and likewise c to d, a to b, r to s, e to f. Applying this forward-one shift to dose gives e, p, t, f, that is eptf. Consistency of the shift across all letters is the key check.

Question 10General Intelligence and Reasoning

Six medicine bottles are stacked one above another. Bottle A is above B, B is above C, and D is above A. Which bottle is lowest among A, B, C and D?

  1. B
  2. C Correct answer.
  3. A
  4. D

Explanation

The relations give a vertical chain D above A, A above B, and B above C. Transitivity places C at the bottom of this group. The lowest bottle is therefore C, since every other named bottle sits above it.

Question 11General Intelligence and Reasoning

A paramedical student's marks in four subjects are in the ratio 3:4:5:6, and the total is 360. What is the highest subject score?

  1. 120 Correct answer.
  2. 90
  3. 96
  4. 108

Explanation

The ratio parts sum to 3+4+5+6 = 18, so one part equals 360 divided by 18, which is 20. The highest share is 6 parts, giving 6 times 20 = 120. Each subject score is obtained by multiplying its ratio part by the value of one part.

Question 12General Intelligence and Reasoning

A doctor is older than the nurse. The pharmacist is younger than the nurse. The technician is older than the doctor. Who is the youngest?

  1. Technician
  2. Pharmacist Correct answer.
  3. Doctor
  4. Nurse

Explanation

Ordering by age: technician is older than doctor, doctor is older than nurse, and nurse is older than pharmacist. This chain places the pharmacist at the bottom. The youngest person is therefore the pharmacist.

Question 13General Intelligence and Reasoning

A hospital notice states: 'If the sample is haemolysed, it must be rejected.' A sample was not rejected. Which conclusion is valid?

  1. The sample was not haemolysed Correct answer.
  2. No sample was haemolysed
  3. The sample was haemolysed
  4. All rejected samples are haemolysed

Explanation

The rule is a conditional: haemolysed implies rejected. Its contrapositive is equally valid: not rejected implies not haemolysed. Since the sample was not rejected, it follows that it was not haemolysed, while claims about all samples or all rejected samples are unsupported.

Question 14General Intelligence and Reasoning

Which number replaces the question mark in the pattern 5, 11, 23, 47, ?

  1. 95 Correct answer.
  2. 94
  3. 96
  4. 93

Explanation

Each term equals double the previous term plus one: 5 doubled plus 1 is 11, 11 doubled plus 1 is 23, and 23 doubled plus 1 is 47. Applying the same rule to 47 gives 94 plus 1, which is 95. Checking the rule against every transition confirms it.

Question 15General Intelligence and Reasoning

A blood bank labels units with two-letter codes using the letters B, L, O, D without repetition. How many such codes can be formed?

  1. 12 Correct answer.
  2. 24
  3. 16
  4. 8

Explanation

For a two-letter code without repetition, the first position has 4 choices and the second has 3 remaining choices. Multiplying gives 4 times 3 = 12 distinct codes. Allowing repetition would instead give 16, which is why the no-repetition condition matters.

Question 16General Intelligence and Reasoning

In a group of 60 patients, 35 are on drip A, 25 on drip B, and 15 are on both. How many are on neither drip?

  1. 15 Correct answer.
  2. 20
  3. 10
  4. 5

Explanation

By inclusion-exclusion, patients on at least one drip number 35 + 25 minus 15 = 45. Subtracting from the total of 60 leaves 15 patients on neither drip. The overlap must be subtracted once to avoid double counting.

Question 17General Intelligence and Reasoning

A clock in the casualty ward shows 3:30. What is the angle between the hour hand and the minute hand?

  1. 90 degrees
  2. 60 degrees
  3. 105 degrees
  4. 75 degrees Correct answer.

Explanation

At 3:30 the minute hand points at 6, that is 180 degrees from 12. The hour hand has moved half of the way from 3 to 4, giving 105 degrees from 12. The difference is 180 minus 105 = 75 degrees.

Question 18General Intelligence and Reasoning

If 1 January of a year falls on Wednesday, what day is 1 February of the same year, assuming January has 31 days?

  1. Friday
  2. Thursday
  3. Saturday Correct answer.
  4. Sunday

Explanation

Thirty-one days after 1 January means advancing 31 days, and 31 divided by 7 leaves a remainder of 3. Moving three weekdays forward from Wednesday gives Saturday. The remainder, not the full day count, determines the weekday shift.

Question 19General Intelligence and Reasoning

A statement reads: 'Every sterilised instrument is safe for use.' Which option is the correct negation of this statement?

  1. Some safe instruments are not sterilised
  2. No sterilised instrument is safe for use
  3. Some sterilised instruments are not safe for use Correct answer.
  4. All safe instruments are sterilised

Explanation

The negation of a universal affirmative is a particular negative: at least one sterilised instrument is not safe for use. Denying the whole claim requires only a single counterexample. The other options either make a stronger contrary claim or reverse the subject and predicate.

Question 20General Intelligence and Reasoning

A nurse walks 6 metres north, turns right and walks 8 metres. How far is the nurse from the starting point?

  1. 10 metres Correct answer.
  2. 12 metres
  3. 2 metres
  4. 14 metres

Explanation

The two legs are perpendicular, forming a right triangle with sides 6 and 8. The straight-line distance is the hypotenuse, found by the square root of 36 plus 64, which is 10 metres. Adding the legs would give the path length, not the displacement.

Question 21General Intelligence and Reasoning

In a code, 'thermometer' is related to 'temperature' the same way 'sphygmomanometer' is related to which quantity?

  1. Pulse rate
  2. Body weight
  3. Blood pressure Correct answer.
  4. Oxygen saturation

Explanation

The analogy pairs an instrument with the quantity it measures: a thermometer measures temperature. A sphygmomanometer is the instrument for measuring blood pressure. The remaining options correspond to different instruments such as a pulse oximeter or weighing scale.

Question 22General Intelligence and Reasoning

A hospital has 5 wards, each with 4 beds per row and 6 rows. If 90 beds are occupied, how many beds are vacant?

  1. 50
  2. 20
  3. 40
  4. 30 Correct answer.

Explanation

Each ward holds 4 times 6 = 24 beds, so five wards hold 5 times 24 = 120 beds. Subtracting the 90 occupied beds leaves 30 vacant beds. Multiplying ward count by beds per ward before subtracting avoids errors.

Question 23General Intelligence and Reasoning

Four lab reports are filed in order of submission: Report 1 before Report 2, Report 3 before Report 1, and Report 4 before Report 3. Which report was submitted first?

  1. Report 4 Correct answer.
  2. Report 2
  3. Report 1
  4. Report 3

Explanation

Chaining the statements gives Report 4 before Report 3, Report 3 before Report 1, and Report 1 before Report 2. The earliest position in this chain belongs to Report 4. Transitive ordering places it ahead of all the others.

Question 24General Intelligence and Reasoning

A pathology lab uses the code 'sample' for 'specimen'. In the same scheme, 'vbnqmf' decodes to which word?

  1. vbnqmf
  2. specimen
  3. testing
  4. sample Correct answer.

Explanation

Each letter of the coded form is one step ahead of the original, so shifting each letter of 'vbnqmf' back by one gives s-a-m-p-l-e. The pair given in the stem establishes this single-step backward shift, and applying it consistently across all six letters yields 'sample'.

Question 25General Intelligence and Reasoning

A ward register lists beds as B1, B4, B9, B16, B25. Which bed number continues the same pattern?

  1. B35
  2. B36 Correct answer.
  3. B30
  4. B49

Explanation

The numbers are perfect squares in order: 1, 4, 9, 16, 25. The next perfect square after 25 is 36, so the following entry is B36.

Question 26General Intelligence and Reasoning

In a hospital, the theatre is 10 m north of the pharmacy. The laboratory is 10 m east of the theatre. The blood bank is 10 m south of the laboratory. Where is the blood bank relative to the pharmacy?

  1. 10 m north
  2. 10 m east Correct answer.
  3. 10 m west
  4. 10 m south

Explanation

Tracing the moves on a grid: north 10, east 10, south 10 returns to the same north-south level as the pharmacy while remaining 10 m to the east. The blood bank therefore lies due east of the pharmacy at the same distance.

Question 27General Intelligence and Reasoning

A patient takes one tablet every 8 hours, starting at 6 a.m. on Monday. At what time does the patient take the fifth tablet?

  1. 6 a.m. Wednesday
  2. 2 p.m. Tuesday
  3. 10 p.m. Monday
  4. 6 a.m. Tuesday Correct answer.

Explanation

The first tablet is at 6 a.m. Monday, and each later dose is 8 hours after the previous one. The fifth tablet comes after four intervals, that is 32 hours later, which is 6 a.m. on Tuesday.

Question 28General Intelligence and Reasoning

In a hospital canteen, 'tea' is called 'syrup', 'syrup' is called 'water', and 'water' is called 'juice'. A patient asks for the drink normally known as water. What will the canteen staff serve?

  1. Water
  2. Tea
  3. Juice Correct answer.
  4. Syrup

Explanation

The question asks what is served when a patient requests the drink ordinarily called water. Since 'water' is renamed 'juice' in this code, the staff would bring what is called juice.

Question 29General Intelligence and Reasoning

Five specimens A, B, C, D and E are placed in a rack from left to right in that order. If A and E are swapped, and then B and D are swapped, which specimen is in the middle position?

  1. D
  2. A
  3. C Correct answer.
  4. E

Explanation

The middle position is the third slot, occupied by C. Swapping A with E exchanges the first and fifth slots, and swapping B with D exchanges the second and fourth slots, leaving the third slot untouched. C therefore remains in the middle.

Question 30General Intelligence and Reasoning

A lab reports that 40% of samples are blood, 25% are urine, and the rest are swabs. If there are 84 swab samples, how many samples are there in total?

  1. 336
  2. 240 Correct answer.
  3. 210
  4. 180

Explanation

Blood and urine together account for 40% + 25% = 65%, so swabs are 35% of the total. If 35% equals 84, then 1% equals 2.4 and 100% equals 240 samples.

Question 31General Intelligence and Reasoning

A ward has nurses and doctors in the ratio 7:3. If 12 more nurses join, the ratio becomes 5:2. How many doctors are there?

  1. 48
  2. 36
  3. 72 Correct answer.
  4. 60

Explanation

Let nurses be 7x and doctors 3x. After 12 nurses join, (7x + 12)/3x = 5/2, giving 14x + 24 = 15x, so x = 24. Doctors are 3x, which equals 72.

Question 32General Intelligence and Reasoning

In a certain code, 'nurse' is written as 'OVTUF' and 'ward' as 'XBSE'. Using the same rule, how is 'dose' written?

  1. DPTF
  2. EPTF Correct answer.
  3. EPSE
  4. FPTF

Explanation

Each letter is replaced by the next letter of the alphabet, and the case is raised to capitals: n→O, u→V, r→S, s→T, e→U. Applying the same shift to d-o-s-e gives E-P-T-F.

Question 33General Intelligence and Reasoning

A notice reads: 'All sterilised instruments are safe to use.' A particular instrument is not safe to use. Which conclusion follows?

  1. Nothing can be concluded about sterilisation.
  2. The instrument was not sterilised. Correct answer.
  3. The instrument was sterilised.
  4. Some sterilised instruments are unsafe.

Explanation

The statement says sterilised implies safe. By contraposition, not safe implies not sterilised, so an unsafe instrument cannot have been sterilised.

Question 34General Intelligence and Reasoning

A nurse's roster repeats a four-day cycle: morning, evening, night, off. If day 1 is morning, what shift falls on day 50?

  1. Night
  2. Morning
  3. Off
  4. Evening Correct answer.

Explanation

The cycle length is 4, so divide 50 by 4, giving remainder 2. The second position in the cycle is evening, so day 50 is an evening shift.

Question 35General Intelligence and Reasoning

In a hospital, the pharmacist is taller than the technician. The technician is taller than the nurse. The doctor is taller than the pharmacist. Who is the shortest?

  1. The technician
  2. The doctor
  3. The nurse Correct answer.
  4. The pharmacist

Explanation

Ordering by height gives doctor > pharmacist > technician > nurse. The nurse stands at the bottom of this chain and is therefore the shortest.

Question 36General Intelligence and Reasoning

In a blood-group code, 'A' stands for 1, 'B' for 2, 'AB' for 3 and 'O' for 4. If a rack holds groups in the order O, A, AB, B, what is the sum of their code values?

  1. 10 Correct answer.
  2. 9
  3. 8
  4. 11

Explanation

Substituting the given values: O = 4, A = 1, AB = 3, B = 2. Adding these gives 4 + 1 + 3 + 2 = 10.

Question 37General Intelligence and Reasoning

A sample is labelled with a two-digit number. The sum of its digits is 9, and reversing the digits increases the number by 27. What is the number?

  1. 45
  2. 54
  3. 63
  4. 36 Correct answer.

Explanation

Let the digits be a and b with a + b = 9. Reversal increases the number by 27, so 9(b − a) = 27, giving b − a = 3. Solving with a + b = 9 yields a = 3 and b = 6, so the number is 36.

Question 38General Intelligence and Reasoning

A hospital corridor has wards on both sides. Ward 7 is directly opposite ward 18, and ward 12 is directly opposite ward 23. Which ward is directly opposite ward 15?

  1. 27
  2. 24
  3. 25
  4. 26 Correct answer.

Explanation

Opposite pairs differ by 11: 18 − 7 = 11 and 23 − 12 = 11. Adding 11 to 15 gives 26, so ward 26 faces ward 15.

Question 39General Intelligence and Reasoning

A lab technician's log shows that the number of tests done doubles every day. On day 4 the lab did 48 tests. On which day did it do 6 tests?

  1. Day 2
  2. Day 3
  3. Day 1 Correct answer.
  4. Day 5

Explanation

Working backwards, halving each day: day 4 = 48, day 3 = 24, day 2 = 12, day 1 = 6. The lab did 6 tests on day 1.

Question 40General Intelligence and Reasoning

In a coding scheme, 'fever' is written as 'gggfs' and 'cough' as 'dpvgi'. Following the same rule, how is 'pain' written?

  1. qajoh
  2. pbjoh
  3. qbjohs
  4. qbjoh Correct answer.

Explanation

Each letter of the word is moved one place forward in the alphabet: f→g, e→f, v→w, e→f, r→s. Applying this to p-a-i-n gives q-b-j-o, written as 'qbjoh'.

Question 41General Awareness and General Knowledge

The BSF is a Central Armed Police Force that functions under the administrative control of which Union Ministry?

  1. Ministry of Defence
  2. Ministry of Home Affairs Correct answer.
  3. Ministry of Labour and Employment
  4. Ministry of External Affairs

Explanation

Border guarding forces such as the BSF, CRPF, CISF, ITBP and SSB are Central Armed Police Forces under the Ministry of Home Affairs. Defence handles the armed forces, not the CAPFs. Knowing the controlling ministry is basic organisational knowledge expected in paramedical recruitment exams.

Question 42General Awareness and General Knowledge

The BSF was raised in 1965 primarily to guard which of the following?

  1. India's rail network
  2. India's embassy premises abroad
  3. India's borders with Pakistan Correct answer.
  4. India's coastline

Explanation

The BSF was constituted in December 1965 largely in response to border tensions with Pakistan, and it guards the India-Pakistan and India-Bangladesh borders in peacetime. Coastal security is handled by the Coast Guard and Navy, and railway security by the RPF.

Question 43General Awareness and General Knowledge

The headquarters of the Border Security Force is located in which city?

  1. Guwahati
  2. Shillong
  3. Srinagar
  4. New Delhi Correct answer.

Explanation

The BSF headquarters is at Block 10, CGO Complex, Lodhi Road, New Delhi. Shillong hosts the headquarters of the BSF's eastern theatre, while Guwahati and Srinagar are sector or frontier-level locations.

Question 44General Awareness and General Knowledge

Which of the following is the highest gallantry award of India?

  1. Shaurya Chakra
  2. Ashoka Chakra
  3. Param Vir Chakra Correct answer.
  4. Vir Chakra

Explanation

The Param Vir Chakra is India's highest wartime gallantry award, while the Ashoka Chakra is the highest peacetime gallantry award. The Vir Chakra and Shaurya Chakra are lower in the order of precedence.

Question 45General Awareness and General Knowledge

In the Indian Constitution, which Fundamental Right is most directly relevant to a paramedical professional's right to practise a lawful occupation?

  1. Right to Equality (Article 14)
  2. Right to Freedom (Article 19) Correct answer.
  3. Right against Exploitation (Article 23)
  4. Cultural and Educational Rights (Article 29)

Explanation

Article 19(1)(g) guarantees the freedom to practise any profession, trade or business, subject to reasonable restrictions under Article 19(6). This is the provision invoked when a person's right to work in a lawful occupation is questioned.

Question 46General Awareness and General Knowledge

Which body conducts the recruitment examination for posts such as constable (paramedical) in the BSF?

  1. National Testing Agency
  2. Staff Selection Commission
  3. Union Public Service Commission
  4. Border Security Force recruitment board Correct answer.

Explanation

Recruitment to non-gazetted posts such as constable (paramedical) in the BSF is conducted through the force's own recruitment process under the Ministry of Home Affairs. UPSC handles gazetted examinations such as the civil services, and SSC handles other central posts.

Question 47General Awareness and General Knowledge

The Tropic of Cancer passes through which Indian state among the following?

  1. Rajasthan Correct answer.
  2. Karnataka
  3. Kerala
  4. Tamil Nadu

Explanation

The Tropic of Cancer passes through eight Indian states, including Rajasthan, Gujarat, Madhya Pradesh, Chhattisgarh, Jharkhand, West Bengal, Tripura and Mizoram. Kerala, Tamil Nadu and Karnataka lie entirely south of it.

Question 48General Awareness and General Knowledge

Which river is known as the 'Sorrow of Bihar' because of its frequent floods?

  1. Damodar
  2. Son
  3. Kosi Correct answer.
  4. Gandak

Explanation

The Kosi river in Bihar shifts its course frequently and causes severe flooding, earning it the name 'Sorrow of Bihar'. The Damodar is called the 'Sorrow of Bengal' for similar reasons.

Question 49General Awareness and General Knowledge

Which Article of the Indian Constitution abolishes untouchability?

  1. Article 25
  2. Article 21
  3. Article 17 Correct answer.
  4. Article 15

Explanation

Article 17 abolishes untouchability and forbids its practice in any form, making it an enforceable fundamental right. Article 15 prohibits discrimination on grounds such as religion, race, caste, sex or place of birth.

Question 50General Awareness and General Knowledge

In the Indian numbering system, one lakh is equal to how many thousands?

  1. 10
  2. 100 Correct answer.
  3. 10,000
  4. 1,000

Explanation

One lakh equals 1,00,000, which is one hundred thousands. This basic place-value conversion is commonly tested in general awareness sections of recruitment exams.
