1. $72 = 9 \times 8$: the number times the number just below it.

2. $12 \times 11 = 132$.

AnswerB · 11

1. Division does not carry over ($36 \div 4 = 9$, but 47 is not a multiple of 4), so look at the digits: $3 + 6 = 9$.

2. For 47: $4 + 7 = 11$.

AnswerB · 7 : 48

1. $24 = 5^2 - 1$: square the first number and subtract 1.

2. Opposites of B, D, F, H: Y, W, U, S, giving YWUS.

AnswerC · TLJKF

1. D→E (+1), R→Q (−1), I→J (+1), V→U (−1), E→F (+1): the letters move forward and back alternately.

2. S+1 = T, M−1 = L, I+1 = J, L−1 = K, E+1 = F, giving TLJKF.

AnswerB · KL : PO

1. G is 7th and T is 20th $(7 + 20 = 27)$, H is 8th and S is 19th $(8 + 19 = 27)$: each letter is replaced by its opposite, in the same order.

2. Opposite of K (11th) is P (16th); opposite of L (12th) is O (15th). So KL : PO matches.

3. KL : OP has the right letters in reverse order; KL : QP starts one letter past the opposite.

AnswerD · Potato

1. Mango, guava and papaya are fruits.

2. Potato is a vegetable (an underground stem, or tuber), so it is the odd one out.

AnswerB · Flute

1. Violin, sitar and guitar are string instruments: they make sound when strings vibrate.

2. A flute is a wind instrument, played by blowing air, so it is the odd one out.

AnswerC · Kilogram

1. Centimetre, kilometre and millimetre are units of length.

2. Kilogram is a unit of mass, so it is the odd one out.

AnswerA · 15

1. 17, 23 and 29 have no factors other than 1 and themselves: they are prime.

2. $15 = 3 \times 5$, so it is not prime and is the odd one out.

AnswerC · 136

1. $36 = 6^2$, $81 = 9^2$ and $169 = 13^2$ are perfect squares.

2. 136 lies between $11^2 = 121$ and $12^2 = 144$, so it is not a perfect square.

AnswerD · RTW

1. In CEG, GIK and MOQ each letter is two places after the one before it (C, skip D, E, skip F, G).

2. In RTW, R→T is 2 places but T→W is 3 places, so RTW is the odd one out.

AnswerA · Bat

1. All four can fly, so flying is not the test.

2. Pigeon, sparrow and parrot are birds: they have feathers and lay eggs.

3. A bat is a mammal: it has fur and feeds its young on milk. So bat is the odd one out.

AnswerD · Bronze

1. Copper, silver and gold are pure metals, each a chemical element.

2. Bronze is an alloy, a mixture made mainly of copper and tin, so it is the odd one out.

AnswerB · 9

1. $8 = 2^3$, $27 = 3^3$ and $64 = 4^3$ are perfect cubes.

2. 9 is $3^2$, a square but not a cube, so it is the odd one out.

AnswerB · 145

1. Add the digits: $1 + 3 + 5 = 9$, $2 + 4 + 3 = 9$, $3 + 5 + 1 = 9$.

2. $1 + 4 + 5 = 10$, so 145 is the odd one out.

AnswerC · 61

1. $51 = 3 \times 17$, $57 = 3 \times 19$ and $87 = 3 \times 29$, so these three are composite (each is divisible by 3).

2. 61 has no factor other than 1 and 61, so it is the only prime and is the odd one out.

AnswerC · 7 : 56

1. In 4 : 16, 6 : 36 and 9 : 81 the second number is the square of the first.

2. $7^2 = 49$, not 56 $(56 = 7 \times 8)$. So 7 : 56 is the odd one out.

AnswerA · JR

1. B (2nd) and Y (25th) are opposite letters: $2 + 25 = 27$. So are D and W $(4 + 23)$ and H and S $(8 + 19)$.

2. J is 10th and R is 18th, and $10 + 18 = 28$. The opposite of J is Q, so JR is the odd one out.

AnswerD · STW

1. In CDF, GHJ and MNP the gaps are +1 then +2 (C→D→F).

2. In STW the gaps are +1 then +3 (S→T→W), so STW is the odd one out.

AnswerA · Trapezium

1. A square, a rhombus and a rectangle each have two pairs of parallel sides, so all three are parallelograms.

2. A trapezium has only one pair of parallel sides, so it is not a parallelogram. It is the odd one out.

AnswerC · 143

1. $119 = 7 \times 17$, $133 = 7 \times 19$ and $217 = 7 \times 31$: all three are multiples of 7.

2. $143 = 11 \times 13$ is not divisible by 7, so it is the odd one out.

AnswerA · KLNQ

1. In BCEI the gaps are +1, +2, +4 (B→C→E→I); DEGK and HIKO have the same +1, +2, +4 gaps.

2. In KLNQ the gaps are +1, +2, +3 (K→L→N→Q), so it is the odd one out.
