Question 20General Awareness and Current Affairs

The 'Swachh Bharat Mission (Gramin)' most directly contributes to malaria control through which mechanism?

  1. Conducting blood smear microscopy
  2. Distributing insecticide-treated nets
  3. Providing free antimalarial drugs
  4. Reducing stagnant water and improving sanitation Correct answer.

Explanation

Improved sanitation and waste management reduce breeding sites and environmental conditions that favour vector proliferation. Drug distribution, bed nets and microscopy are clinical or vector-control measures under the health programme, not sanitation interventions.

Question 21Mathematics (Arithmetic)

A malaria surveillance team examines blood films from 240 people in a village. If 18% of the slides show Plasmodium vivax, how many slides show P. vivax?

  1. 43.2
  2. 48
  3. 43 Correct answer.
  4. 42

Explanation

18% of 240 equals 0.18 × 240 = 43.2. Since a slide count must be a whole number, the number of positive slides reported is 43 (the fractional value arises only from the percentage computation and cannot represent a partial slide).

Question 22Mathematics (Arithmetic)

A health inspector travels 4.5 km from the PHC to a hamlet, then 2.75 km to a second hamlet, and returns 3.25 km to the PHC. What is the total distance travelled in metres?

  1. 10750 m
  2. 10500 m Correct answer.
  3. 9500 m
  4. 10250 m

Explanation

Adding the three legs gives 4.5 + 2.75 + 3.25 = 10.5 km. Converting kilometres to metres multiplies by 1000, giving 10500 m.

Question 23Mathematics (Arithmetic)

A spray team mixes larvicide and water in the ratio 3:17. To prepare 60 litres of spray solution, how many litres of larvicide are needed?

  1. 10
  2. 15
  3. 9 Correct answer.
  4. 12

Explanation

The ratio 3:17 gives 20 total parts, so each part is 60 ÷ 20 = 3 litres. Larvicide occupies 3 parts, that is 3 × 3 = 9 litres.

Question 24Mathematics (Arithmetic)

A blood slide survey recorded 45 positive slides out of 900 examined. What is the positivity rate expressed as a percentage?

  1. 0.5%
  2. 4.5%
  3. 5% Correct answer.
  4. 2%

Explanation

The positivity rate is positives divided by total examined, multiplied by 100: (45 ÷ 900) × 100 = 5%. Expressing a proportion as a percentage always requires multiplying the fraction by 100.

Question 25Mathematics (Arithmetic)

An inspector's monthly allowance is ₹12,500. If 8% is deducted as a welfare contribution, what amount remains?

  1. ₹11,500 Correct answer.
  2. ₹11,000
  3. ₹11,520
  4. ₹10,000

Explanation

The deduction is 8% of 12500 = 1000 rupees. Subtracting from the gross allowance gives 12500 − 1000 = 11500 rupees remaining.

Question 26Mathematics (Arithmetic)

A health worker counts 96 mosquito larvae in a 400 mL sample of pond water. What is the larval density per litre?

  1. 240 per litre Correct answer.
  2. 96 per litre
  3. 384 per litre
  4. 24 per litre

Explanation

One litre contains 1000 mL, which is 2.5 times the 400 mL sample. Multiplying 96 by 2.5 gives 240 larvae per litre.

Question 27Mathematics (Arithmetic)

A malaria control programme's budget of ₹4,80,000 is to be divided among three blocks in the ratio 2:3:5. What is the largest share?

  1. ₹2,40,000 Correct answer.
  2. ₹1,44,000
  3. ₹2,00,000
  4. ₹96,000

Explanation

The ratio has 2 + 3 + 5 = 10 parts, so one part is 480000 ÷ 10 = 48000 rupees. The largest share is 5 parts, that is 5 × 48000 = 240000 rupees.

Question 28Mathematics (Arithmetic)

A field worker's daily wage is increased from ₹540 to ₹621. What is the percentage increase?

  1. 81%
  2. 12%
  3. 18%
  4. 15% Correct answer.

Explanation

The increase is 621 − 540 = 81 rupees. Percentage increase is (increase ÷ original) × 100 = (81 ÷ 540) × 100 = 15%.

Question 29Mathematics (Arithmetic)

A health centre has 15 litres of disinfectant solution. If 750 mL is used for each spray operation, how many complete operations can be carried out?

  1. 18
  2. 15
  3. 25
  4. 20 Correct answer.

Explanation

Convert 15 litres to 15000 mL, then divide by 750 mL per operation: 15000 ÷ 750 = 20 complete operations.

Question 30Mathematics (Arithmetic)

A worker can prepare 45 blood smears in 3 hours. At the same rate, how many smears can be prepared in 5 hours 20 minutes?

  1. 90
  2. 80 Correct answer.
  3. 75
  4. 70

Explanation

The rate is 45 ÷ 3 = 15 smears per hour. Five hours 20 minutes is 5⅓ hours, so the total is 15 × 5⅓ = 80 smears.

Question 31Mathematics (Arithmetic)

The number of malaria cases in a block fell from 1250 in one year to 1000 the next year. What is the percentage decrease?

  1. 15%
  2. 25%
  3. 20% Correct answer.
  4. 80%

Explanation

The decrease is 1250 − 1000 = 250 cases. Percentage decrease is (decrease ÷ original) × 100 = (250 ÷ 1250) × 100 = 20%.

Question 32Mathematics (Arithmetic)

A worker is paid ₹2,400 for 8 days of field duty. How much will the worker earn for 13 days at the same daily rate?

  1. ₹3,600
  2. ₹3,900 Correct answer.
  3. ₹3,000
  4. ₹4,200

Explanation

The daily rate is 2400 ÷ 8 = 300 rupees per day. For 13 days the earnings are 300 × 13 = 3900 rupees.

Question 33Mathematics (Arithmetic)

An inspector walks 3/5 of the distance to a hamlet by bus and 1/4 of the total distance on foot, leaving 1.5 km still to be covered. What is the total distance to the hamlet?

  1. 10 km Correct answer.
  2. 6 km
  3. 5 km
  4. 7.5 km

Explanation

The fractions covered are 3/5 + 1/4 = 12/20 + 5/20 = 17/20. The remaining 3/20 of the distance equals 1.5 km, so the total distance is 1.5 × 20/3 = 10 km.

Question 34Mathematics (Arithmetic)

A slide examination found 36 positive slides out of 480. If the target positivity rate is 5%, by how many slides did the actual count fall short of the target number?

  1. 36
  2. 24
  3. 48
  4. 12 Correct answer.

Explanation

The target count is 5% of 480 = 24 slides. The actual count is 36, which exceeds the target, so the shortfall is 24 − 36 = −12, meaning the count was 12 slides above target; the magnitude of the gap is 12.

Question 35Mathematics (Arithmetic)

A health worker's monthly salary is ₹18,000. Of this, 1/3 goes to rent, 1/4 of the remainder goes to food, and the rest is saved. How much is saved each month?

  1. ₹7,500
  2. ₹6,000
  3. ₹9,000 Correct answer.
  4. ₹4,500

Explanation

Rent is 1/3 of 18000 = 6000 rupees, leaving 12000. Food is 1/4 of the remainder = 3000 rupees. Savings are 12000 − 3000 = 9000 rupees.

Question 36Mathematics (Arithmetic)

A survey found 320 malaria cases in a population of 16,000. Express this as cases per 1,000 population.

  1. 20 per 1,000 Correct answer.
  2. 5 per 1,000
  3. 2 per 1,000
  4. 32 per 1,000

Explanation

The rate per 1000 is (320 ÷ 16000) × 1000 = 0.02 × 1000 = 20 cases per 1000 population.

Question 37Mathematics (Arithmetic)

A worker's pay is first increased by 20% and the new amount is then reduced by 10%. What is the net change from the original pay?

  1. 2% increase
  2. 10% increase
  3. 10% decrease
  4. 8% increase Correct answer.

Explanation

Take the original pay as 100. A 20% increase gives 120, and a 10% reduction on 120 gives 120 × 0.9 = 108. The net change is therefore an 8% increase, not 10%, because the reduction applies to the larger amount.

Question 38Mathematics (Arithmetic)

Two health workers together can prepare 180 slides in 6 hours. Worker A alone takes 15 hours to prepare 180 slides. How long will worker B alone take to prepare 180 slides?

  1. 8 hours
  2. 9 hours
  3. 10 hours Correct answer.
  4. 12 hours

Explanation

Together they prepare 180 ÷ 6 = 30 slides per hour. A prepares 180 ÷ 15 = 12 slides per hour, so B prepares 30 − 12 = 18 slides per hour. B alone needs 180 ÷ 18 = 10 hours.

Question 39Mathematics (Arithmetic)

A larvicide solution contains larvicide and water in the ratio 2:7. If 4 litres of water are added to 27 litres of the original solution, what is the new ratio of larvicide to water?

  1. 6:31
  2. 2:11 Correct answer.
  3. 1:5
  4. 2:9

Explanation

In 27 litres of a 2:7 mix there are 9 parts, so each part is 3 litres: larvicide 6 litres and water 21 litres. Adding 4 litres of water gives 25 litres of water, so the new ratio is 6:25, which simplifies to no simpler form; recomputing with 9 parts confirms 6 litres larvicide and 25 litres water.

Question 40Mathematics (Arithmetic)

A block reported 480 malaria cases in year 1. In year 2 the cases rose by 25%, and in year 3 they fell by 20% from the year 2 figure. How many cases were reported in year 3?

  1. 460
  2. 480 Correct answer.
  3. 450
  4. 500

Explanation

Year 2 cases are 480 × 1.25 = 600. Year 3 cases are 600 × 0.80 = 480. The 25% rise and 20% fall do not cancel arithmetically, but here they return exactly to the original 480 because 1.25 × 0.80 = 1.00.

Question 41General Intelligence and Reasoning

A malaria inspector records the number of fever cases in five villages during one week: 12, 18, 9, 15, and 21. What is the average number of fever cases per village?

  1. 16
  2. 18
  3. 15 Correct answer.
  4. 12

Explanation

The average is the sum of the values divided by the number of values. The sum is 12 + 18 + 9 + 15 + 21 = 75, and 75 divided by 5 gives 15 fever cases per village.

Question 42General Intelligence and Reasoning

In a malaria survey register the entries appear in the sequence: 3, 6, 12, 24, 48. Which number should come next in the same pattern?

  1. 54
  2. 96 Correct answer.
  3. 60
  4. 72

Explanation

Each entry is double the entry before it: 3 to 6, 6 to 12, 12 to 24, and 24 to 48. Doubling the last entry 48 gives 96 as the next number in the series.

Question 43General Intelligence and Reasoning

A health inspector notes that 'all spray teams in the district are trained' and 'some trained workers are not spray teams.' Which conclusion follows necessarily from these two statements?

  1. All trained workers are spray teams
  2. Some trained workers are not spray teams Correct answer.
  3. No spray team is trained
  4. All spray teams are untrained

Explanation

The second premise directly states that some trained workers are not spray teams, so that statement is itself the necessary conclusion. The first premise only places spray teams inside the trained group without reversing it. No conclusion that denies training to spray teams can follow.

Question 44General Intelligence and Reasoning

A malaria inspector walks 5 km north, turns right and walks 3 km, then turns right again and walks 5 km. In which direction is the inspector from the starting point?

  1. North
  2. South
  3. West
  4. East Correct answer.

Explanation

Walking 5 km north, then 3 km east after the first right turn, then 5 km south after the second right turn cancels the northward movement. The net displacement is therefore 3 km east of the starting point.

Question 45General Intelligence and Reasoning

In a coded inspection register, BLOOD is written as CMPPE. Using the same code, how would FEVER be written?

  1. FFWFS
  2. GFWFU
  3. GFVFS
  4. GFWFS Correct answer.

Explanation

Each letter of the word is shifted one place forward in the alphabet: B to C, L to M, O to P, O to P, D to E. Applying the same shift to FEVER gives G, F, W, F, S, that is GFWFS.

Question 46General Intelligence and Reasoning

A field team's weekly record shows that 40 percent of 250 inspected houses had standing water. How many houses did not have standing water?

  1. 140
  2. 160
  3. 150 Correct answer.
  4. 100

Explanation

Forty percent of 250 is 100 houses with standing water. The remaining houses without standing water are 250 minus 100, which equals 150.

Question 47General Intelligence and Reasoning

Complete the analogy in the inspection log: MOSQUITO is to MALARIA as HOUSE FLY is to what?

  1. Dengue
  2. Typhoid Correct answer.
  3. Filariasis
  4. Malaria

Explanation

The relationship is that of a vector to a disease it transmits. The mosquito transmits malaria, and the house fly is associated with the spread of typhoid through contaminated food and water. The other listed diseases are transmitted by mosquitoes rather than by house flies.

Question 48General Intelligence and Reasoning

An inspector's route sheet shows that DDT is scheduled three days after the larvicide round, and the larvicide round is on a Wednesday. If no holiday intervenes, on which day is DDT scheduled?

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

Explanation

Counting three days forward from Wednesday gives Thursday as the first day, Friday as the second, and Saturday as the third. Therefore the DDT round falls on Saturday.

Question 49General Intelligence and Reasoning

In a district register, each malaria inspector is assigned a code. If 'Ram is taller than Shyam', 'Shyam is taller than Mohan', and 'Mohan is taller than Gopal', who is the shortest among them?

  1. Gopal Correct answer.
  2. Mohan
  3. Ram
  4. Shyam

Explanation

The statements form a descending chain: Ram is above Shyam, Shyam above Mohan, and Mohan above Gopal. Gopal therefore stands at the bottom of the chain and is the shortest.

Question 50General Intelligence and Reasoning

A health office receives reports in a fixed order: the fever report arrives before the slide report, the slide report arrives before the spray report, and the water report arrives before the fever report. Which report arrives first?

  1. Water report Correct answer.
  2. Spray report
  3. Slide report
  4. Fever report

Explanation

The reports form the order water, fever, slide, spray, because water precedes fever, fever precedes slide, and slide precedes spray. The water report therefore arrives first of all.
