QUESTION KEY SOLUTION STRAND LEVEL OF DIFFICULTY

1 A

The temperature of an ice-cream is very close to the freezing point of water (0 °C) Noticing the given scale, the closest point to °C is option A

Measurement Easy

2 C Multiplying by 50 gives 250 Number and Arithmetic Easy

3 B

This number should have digits If we write it using expanded notation, we should have 400 000 + 600 + In other words, it is 400 602

Number and

Arithmetic Easy

4 C

Reading the code from left to right from the upper left corner and using the key provided, option C is the only code that shows correctly all digits of the given number

Number and

Arithmetic Easy

5 A The 3D shape is made of four rectangles and two pentagons. Measurement Medium

6 C

Trent made his pattern by skipping squares systematically by 2, then 3, then 4, then squares

Following this pattern, he will skip squares to shade the next square Therefore, the next shaded number in Trent’s pattern will be 26

Number and

Arithmetic Medium

7 B

Convert hours to minutes and m to cm first The snail travelled 1.5 m in hours That is equal to 150 cm in 240

Distance travelled in = 150240 cm 150240 × 160

Distance travelled in 160 = 150

240 150240 × 160 cm

= 100 cm

Level of difficulty refers to the expected level of difficulty for the question.

Easy more than 70% of candidates will choose the correct option

Medium about 50–70% of candidates will choose the correct option

Medium/Hard about 30–50% of candidates will choose the correct option

Hard less than 30% of candidates will choose the correct option

8 B

The ratio of the number of teeth on the cogs can be expressed as a ratio of their circumference which in turn can be expressed as a ratio of their radii

X:Y:Z = : : 12 = : ½ : 3/2

Cog X has twice the number of teeth as cog Y, so when cog X makes a complete revolution, cog Y must make revolutions

Cog X has 2/3 of the number of teeth of cog Z, so when cog X makes a complete revolution, cog Z makes 2/3 revolutions When cog X makes 15 revolutions, cog Y makes 30 revolutions and cog Z makes 10 revolutions

Algebra and

Pattern Medium/Hard

9 A

The difference between ắ and ẵ is ẳ

Therefore, if we turn the sign ắ turn clockwise,

, then ½ turn anticlockwise, , then the result will be the same as just turning the sign ¼ turn clockwise

Space and

Geometry Hard

If a cube has a volume of 343 cm3 then its edge

length is cm There are 12 edges on a cube, so the total length of the edges is × 12 = 84 cm
