QUESTION KEY SOLUTION STRAND LEVEL OF DIFFICULTY

1 C The picture in (C) has squares and cirlces Space and Geometry Easy

2 B Measure the lines Line B is the longest Measurement Easy

3 B There are six packs of ten nails (that is 60 nails) and seven nails left over; together they make 67. Number and Arithmetic Easy D The image is a reflection of the letter ‘F’ on the spine of the book. Space and Geometry Easy

5 C

$5 + × $2 + 50c + 5c + × 20c + × 10c = $10.15

or

$5 + $2 + $2 + 50c + 5c + 20c + 20c + 10c + 10c = $10.15

Number and

Arithmetic Easy

6 B

Brooke received 45c change She could get two 20c coins and one 5c coin (altogether coins) or four 10c coin and one 5c coin (altogether coins) The first combination has the least number of coins

Number and

Arithmetic Medium

7 B

Estimates the total number of seats The top and bottom areas are equal, with 1000 seats each The area on the left-hand side is equal to the area in the right-hand side and can accommodate about 600 seats each

Total estimate = 1000 + 1000 + 600 + 600

Number and

Arithmetic Medium

8 D

The possibilities when tossing two coins together are: (head, head); (tail, tail); (head, tail); (tail, head) There are two possibilities of getting one head and one tail (the order does not matter) out of four Therefore, the answer is out of

Chance and

(10)

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

9 C

Create a systematic list of all combinations Here is the way to it:

Use letters to represent the beads Y – for a yellow bead

B – for a blue bead R – for a red bead G – for a green bead

The first arrangement could be: Y B R G

The second arrangement could be: Y B G R

The third arrangement could be: Y R B G

The fourth arrangement could be: Y R G B

The fifth could be: Y G B R

and the sixth arrangement could be: Y G R B

Having the yellow bead at the beginning produces six different arrangements In fact, having any of the four beads as the first bead generates six different arrangements Therefore, 24 different arrangements can be produced

Chance and

Data Hard

10 B

Six chocolate buttons cost the same as four red frogs This means that three chocolate buttons cost the same as two red frogs Therefore, count by threes to calculate that chocolate buttons cost as much as red frogs, chocolate buttons cost as much as red frogs, 12

chocolate buttons cost as much as red frogs and 15 chocolate buttons cost as much as 10 red frogs Therefore, the correct answer is 15
