Question 8Higher order thinking and problem-solving
In a code, CAT is written as DBU. Using the same rule, how is DOG written?
- EPH Correct answer.
- EOH
- CPF
- EPG
Explanation
Each letter is replaced by the next letter of the alphabet: C→D, A→B, T→U. Applying the same shift to DOG gives D→E, O→P, G→H, which is EPH.
Question 9Higher order thinking and problem-solving
A bag holds 4 red and 6 blue counters. Two counters are drawn without replacement. What is the probability that both are red?
- 2/15 Correct answer.
- 8/45
- 4/25
- 1/5
Explanation
The chance the first is red is 4/10 = 2/5. Given that, 3 red remain among 9 counters, so the second is red with probability 3/9 = 1/3. Multiplying gives 2/5 × 1/3 = 2/15.
Question 10Higher order thinking and problem-solving
Three friends share some stickers. Amy gets half, Ben gets one third, and Cara gets the remaining 4 stickers. How many stickers were shared in total?
- 24 Correct answer.
- 30
- 12
- 18
Explanation
Amy and Ben take 1/2 + 1/3 = 5/6 of the stickers, leaving 1/6 for Cara. Since 1/6 of the total is 4, the total is 4 × 6 = 24.

Question 17Higher order thinking and problem-solving
Some bloops are razzes. No razz is a zint. Which conclusion must be true?
- Some bloops are not zints Correct answer.
- Some zints are razzes
- All zints are bloops
- No bloop is a zint
Explanation
The bloops that are razzes cannot be zints, since no razz is a zint. Therefore at least some bloops are not zints. The other options go beyond what the premises guarantee.
Question 18Higher order thinking and problem-solving
A sequence alternates: 3, 6, 4, 8, 6, 12, 10, ... What is the next term?
- 18

- 44 square metres Correct answer.
- 40 square metres
Explanation
The outer rectangle including the path is 14 m by 10 m, with area 140 square metres. The garden itself is 96 square metres, so the path is 140 − 96 = 44 square metres.
Question 20Higher order thinking and problem-solving
Four cards each have a letter on one side and a number on the other. The rule is: if a card has a vowel, it has an even number on the other side. Which card must be turned over to test the rule?
- The card showing the letter A
- The card showing a consonant
- The card showing an even number
- The card showing an odd number Correct answer.
Explanation
A rule of the form 'if vowel then even' can only be broken by a vowel with an odd number, or by an odd number paired with a vowel. Turning the odd-number card checks whether its reverse is a vowel.
Question 21Higher order thinking and problem-solving
A cube is painted on all outer faces and then cut into 27 equal smaller cubes. How many of the small cubes have exactly two painted faces?
- 8
- 18
- 6
- 12 Correct answer.
Explanation
In a 3×3×3 cut, the cubes with two painted faces lie along the edges but not at the corners. A cube has 12 edges, and each edge contributes one such cube, giving 12.
Question 22Higher order thinking and problem-solving
A jug holds 5 litres and another holds 3 litres, with no markings. How can exactly 4 litres be measured using only these two jugs and a tap?
- Fill the 5 L jug and pour out half by eye
- Fill the 3 L jug, pour it into the 5 L jug, then fill the 3 L jug again
- Fill the 3 L jug twice and combine the amounts
- Fill the 5 L jug, pour into the 3 L jug, empty the 3 L jug, pour the rest into it, then fill the 5 L jug and top up the 3 L jug Correct answer.
Explanation
Fill the 5 L jug, pour 3 L into the 3 L jug leaving 2 L in the 5 L jug. Empty the 3 L jug, pour the 2 L into it, then fill the 5 L jug and top up the 3 L jug (which needs 1 L). The 5 L jug now holds exactly 4 L.
Question 23Higher order thinking and problem-solving
A sequence follows the rule: each term is the sum of the two previous terms. If the 5th term is 11 and the 6th term is 18, what is the 2nd term?
- 3 Correct answer.
- 7
- 5
- 4
Explanation
Working backwards, the 4th term is 18 − 11 = 7, the 3rd is 11 − 7 = 4, and the 2nd is 7 − 4 = 3. Checking forward: 3, 4, 7, 11, 18 fits the rule.
Question 24Higher order thinking and problem-solving
In a class, every student studies at least one of art or music. 20 study art, 14 study music, and 6 study both. How many students are in the class?
- 28 Correct answer.
- 34
- 30
- 40
Explanation
Since everyone studies at least one subject, the class size is the size of the union: 20 + 14 − 6 = 28. The overlap is counted twice and must be subtracted once.
Question 25Higher order thinking and problem-solving
A statement says: 'Every honest person returns lost property.' A person returns lost property. Which conclusion follows logically?
- The person must be honest
- The person may or may not be honest Correct answer.
- The person cannot be honest
- The person is definitely dishonest
Explanation
The statement only says honesty guarantees returning property; it does not say only honest people do so. A dishonest person could also return property, so honesty cannot be concluded.
Question 26Higher order thinking and problem-solving
A tank fills at 6 litres per minute and drains at 4 litres per minute. Starting empty, how long until it holds 30 litres?
- 3 minutes
- 15 minutes Correct answer.
- 5 minutes
- 30 minutes
Explanation
The net gain per minute is the fill rate minus the drain rate, 6 − 4 = 2 litres per minute. Dividing the target volume by the net rate gives 30 ÷ 2 = 15 minutes.
Question 27Higher order thinking and problem-solving
Four tiles are laid in a row, numbered 1 to 4 from left to right. The red tile is immediately right of the blue tile. The green tile is at position 1. Which tile is at position 2?
- Blue Correct answer.
- Red
- Cannot be determined
- Green
Explanation
Green occupies position 1, so the red-blue adjacent pair must sit in positions 2–3 or 3–4. Since red is immediately right of blue, blue must be at position 2 and red at position 3.
Question 28Higher order thinking and problem-solving
A square has area 49 cm². A second square has sides twice as long as the first. What is the area of the second square?
- 343 cm²
- 147 cm²
- 196 cm² Correct answer.
- 98 cm²
Explanation
The first square has side 7 cm. Doubling the side gives 14 cm, and 14 × 14 = 196 cm². Doubling a length multiplies area by 4, and 49 × 4 = 196.
Question 29Higher order thinking and problem-solving
A code uses the rule: shift each letter forward by 2, then reverse the order of the letters. Applying this rule to the word BAT gives which result?
- VTU
- VTC
- VCD Correct answer.
- DCV
Explanation
Shifting B, A, T forward by 2 gives D, C, V. Reversing that order gives V, C, D, so the coded word is VCD.
Question 30Higher order thinking and problem-solving
A pattern of dots grows so that figure 1 has 1 dot, figure 2 has 4 dots, figure 3 has 9 dots, and figure 4 has 16 dots. How many dots will figure 7 have?
- 36
- 49 Correct answer.
- 42
- 56
Explanation
The number of dots in figure n is n squared, since 1, 4, 9, 16 are the square numbers. For figure 7 the count is 7 × 7 = 49.
Question 31Higher order thinking and problem-solving
A jar contains only black and white marbles. The probability of drawing a black marble is 3/5. If the jar holds 40 marbles, how many white marbles are in it?
- 24
- 8
- 16 Correct answer.
- 25
Explanation
Black marbles number 3/5 of 40, which is 24. The remaining marbles are white, so 40 − 24 = 16.
Question 32Higher order thinking and problem-solving
In a survey, 12 people like tea only, 9 like coffee only, and 5 like both. How many people were surveyed in total?
- 17
- 26 Correct answer.
- 31
- 21
Explanation
Everyone surveyed falls into one of three groups: tea only, coffee only, or both. Adding these disjoint groups gives 12 + 9 + 5 = 26.
Question 33Higher order thinking and problem-solving
A clock shows 4:30. What is the size of the smaller angle between the hour hand and the minute hand?
- 75°
- 30°
- 45° Correct answer.
- 60°
Explanation
At 4:30 the minute hand points at 6, which is 180° from 12. The hour hand has moved half way from 4 to 5, sitting at 135° from 12. The difference is 180 − 135 = 45°.
Question 34Higher order thinking and problem-solving
A number machine doubles its input and then adds 7. A second machine subtracts 3 and then triples the result. If the first machine's output is fed into the second, and the final output is 36, what was the original input?
- 4
- 1 Correct answer.
- 3
- 2
Explanation
Working backwards from 36, divide by 3 to get 12, then add 3 to get 15, which is the first machine's output. Solving 2x + 7 = 15 gives x = 4... checking forwards: 2(1)+7 = 9, then 3(9−3) = 18, which is not 36, so the input must satisfy 3(2x+7−3)=36, giving 2x+4=12 and x=4.
Question 35Higher order thinking and problem-solving
A sequence is built by multiplying the previous term by 2 and then subtracting 1: 2, 3, 5, 9, 17, ... What is the next term?
- 34
- 33 Correct answer.
- 31
- 35
Explanation
Applying the rule to the last term: 17 × 2 = 34, then 34 − 1 = 33. Checking earlier terms confirms the rule, since 9 × 2 − 1 = 17.
Question 36Higher order thinking and problem-solving
A cube is painted and then cut into 64 equal smaller cubes. How many of the small cubes have exactly two painted faces?
- 8
- 12
- 16
- 24 Correct answer.
Explanation
A 4×4×4 cut produces cubes with two painted faces only along the edges, excluding corners. Each of the 12 edges contributes 4 − 2 = 2 such cubes, giving 12 × 2 = 24.
Question 37Higher order thinking and problem-solving
Three switches outside a room each control one bulb inside it. You may enter the room only once. What is the minimum number of switches you must operate before entering to identify which switch controls which bulb?
- One
- It cannot be done with one entry
- Three
- Two Correct answer.
Explanation
Turn on the first switch and leave it on for several minutes, then turn it off and turn on the second. Entering the room, the lit bulb matches the second switch, the warm dark bulb matches the first, and the cold dark bulb matches the third.
Question 38Higher order thinking and problem-solving
A box contains 5 red, 3 green and 2 yellow balls. Balls are drawn at random without looking. What is the smallest number that must be drawn to guarantee at least two balls of the same colour?
- 3
- 6
- 5
- 4 Correct answer.
Explanation
There are three colours, so the worst case is drawing one of each colour in the first three draws. The fourth draw must repeat a colour, guaranteeing a matching pair.
Question 39Higher order thinking and problem-solving
In a certain town, everyone who owns a bicycle also owns a helmet. Some helmet owners own a bicycle. Which statement must be true?
- Some helmet owners do not own a bicycle
- No helmet owner lacks a bicycle Correct answer.
- Some bicycle owners do not own a helmet
- Everyone who owns a helmet owns a bicycle
Explanation
The first sentence says bicycle owners are a subset of helmet owners, so no helmet owner can lack a bicycle. The second sentence merely confirms the subset is non-empty.
Question 40Higher order thinking and problem-solving
A farmer has 17 sheep. All but 9 run away. How many sheep remain?
- 17
- 0
- 8
- 9 Correct answer.
Explanation
The phrase 'all but 9' means every sheep except 9 left, so 9 sheep stay behind. The total of 17 is a distractor that invites subtracting 9 from it.
Question 41Reasoning
A train travels 180 km in 3 hours. At the same average speed, how far will it travel in 5 hours?
- 300 km Correct answer.
- 270 km
- 360 km
- 240 km
Explanation
The speed is 180 ÷ 3 = 60 km per hour. In 5 hours the train covers 60 × 5 = 300 km.
Question 42Reasoning
Find the next number in the sequence: 2, 6, 12, 20, 30, ...
- 36
- 40
- 44
- 42 Correct answer.
Explanation
The differences between consecutive terms are 4, 6, 8, 10, so the next difference is 12. Adding 12 to 30 gives 42.
Question 43Reasoning
All roses in the garden are red. Some red flowers in the garden are tulips. Which statement must be true?
- Some red flowers in the garden are roses. Correct answer.
- Every red flower in the garden is a rose.
- Some roses in the garden are tulips.
- All tulips in the garden are roses.
Explanation
Since all roses are red, every rose is a red flower, so some red flowers are roses. The tulip information does not force any link between tulips and roses.
Question 44Reasoning
Which word does not belong with the others?
- Iron
- Copper
- Granite Correct answer.
- Zinc
Explanation
Copper, iron and zinc are all metals, while granite is a rock. The odd one out is the non-metal.

Each term is multiplied by 3, so the next term is 81 × 3 = 243.
Question 49Reasoning
Five friends sit in a row. Amy is to the left of Ben. Ben is to the left of Cara. Dan is to the right of Cara. Who must be to the left of Dan?
- Only Cara
- Only Amy and Ben
- Amy, Ben and Cara Correct answer.
- Only Ben
Explanation
The chain Amy < Ben < Cara < Dan places Amy, Ben and Cara all to the left of Dan. Therefore all three must be left of Dan.
Question 50Reasoning
A shirt is reduced by 20% and then the reduced price is reduced by a further 10%. What is the total percentage reduction from the original price?
- 27%
- 28% Correct answer.
- 30%
- 32%
Explanation
After 20% off, 80% remains. A further 10% off leaves 80% × 90% = 72% of the original, so the total reduction is 28%.
