Question 7 [3 marks]
Tamwar buys
4 packets of rice, costing 50p each
1 box of cereal costing £1.20
2 tins of beans
Tamwar pays with a £5 note.
He gets £1 change.
What is the price of one tin of beans?
Give your answer in pence.
Answer type: Simple text answer
ANSWER: 40p
WORKING:
Let the price of a tin of beans be x
4 \times £0.50 = £2.00
1 \times £1.20 = £1.20
2 \times x = 2x
Total = 2 + 1.20 + 2x = 3.20 + 2x
5.00 - 1.00 = £4.00 spent
3.20 + 2x = 4.00
2x = 0.80
x = £0.40 = 40p
Question 8
Answer the following questions.
Question 8(a) [1 mark]
Work out \dfrac{2}{9} \times \dfrac{2}{3}
Answer type: Fraction
ANSWER: \dfrac{4}{27}

Question 9 [4 marks]
Kimberley works for a company.
Her normal rate of pay is £13 per hour.

Kimberley’s rate of overtime is 1.5 times her normal rate of pay per hour.
On Friday, Kimberley works for 12 hours.
How much did she earn on Friday?
Answer type: Simple text answer
ANSWER: £169
WORKING:
Overtime rate = 1.5 \times £13 = £19.50 per hour
She works 10 hours at normal pay and 2 hours at overtime pay
She earns (10 \times £13) + (2 \times £19.50) = £169

Question 11
A sequence of patterns is made from square shapes and triangle shapes
Below are the first three patterns in the sequence.
Question 11(a) [2 marks]
How many square shapes are needed to make pattern 5?
Answer type: Simple text answer
ANSWER: 9
WORKING:
1, 3, 5, ...If we carry on the sequence we get 7 for pattern 4 and then 9 for pattern 5
(The nth term is 2n-1)
Question 11(b) [2 marks]
How many triangle shapes are needed for pattern 30?
Answer type: Simple text answer
ANSWER: 120
WORKING:
4,8,12,...The nth term is 4n

Question 11(c) [2 marks]
What is the total number of shapes needed for pattern 10?
Answer type: Simple text answer
ANSWER: 59
WORKING:
If we add the nth terms together for both sequences, we get (2n-1) + (4n) = 6n-1.
So for pattern 10 there are 6 \times 10 - 1 = 59 shapes in total.
Question 12 [2 marks]
There are 5 red crayons, 10 pink crayons and 7 purple crayons in a box.

ANSWER: B
WORKING:
No, we don’t have any figures for the second group, just angles, so we don’t know how many people had brown eyes.
Question 15 [4 marks]
Below is a triangle and a square.
The area of the triangle is twice the area of the square.
Work out the length, x, of one side of the square.
Answer type: simple text
ANSWER: x= 6 cm
WORKING:
Area of triangle = \dfrac{1}{2} \times 16 \times 9 = 72 cm^2
Area of square = 72 \div 2 = 36 cm^2
Area of square = 36 = x^2
x = \sqrt{36} = 6 cm

Question 17 [4 marks]
6 bars of chocolate have a total weight of 900 g
4 bars of chocolate and 2 packets of chocolate have a total weight of 820 g
What is the total weight of 5 bars of chocolate and 3 packets of chocolate?
Answer type: Simple text answer
ANSWER: 1080 g
WORKING:
Let b be the weight of one bar, and p be the weight of one packet.
b = 900 \div 6 = 150 g
4b + 2p = 820
4(150) + 2p = 820
600 + 2p = 820
2p = 220
p = 110 g
5b + 3p = 5(150) + 3(110) = 1080 g
Question 18
Larissa has a garden in the shape of a circle of radius 5 m
She is going to cover the garden with lawn feed.
Lawn feed is sold in bottles.

Question 23 [3 marks]
Work out 46.3 \times 5.2
Answer type: Simple text answer
ANSWER: 240.76
WORKING:
Move the decimal places on each number, to make them easier to use to calculate.
20000 + 3000 + 150 = 23150
800 + 120 + 6 = 926
23150 + 926 = 24076

Question 25 [5 marks]
A rectangular frame is made from 5 straight pieces of metal, as seen below.
The mass of the metal is 2.5 kg per metre.
What is the total mass of the metal in this frame?
Answer type: Simple text answer
ANSWER: 95 kg
WOKRING:
Calculate the length of the diagonal by using Pythagoras’ theorem:
\sqrt{6^2 + 8^2} = \sqrt{100} = 10 m
Add together the lengths of all five pieces of metal:
6+6+8+8+10 = 38 m
Multiply this by 2.5 kg to calculate the total mass of the frame:
38 \times 2.5 = 95 kg
Question 26 [2 marks]
The equation of line A is y = 4x - 1
The equation of line B is 2y - 8x - 9 = 0
Are these two lines parallel, perpendicular or neither?
Answer type: Multiple choice type 1
A: Parallel
B: Perpendicular
C: Neither
ANSWER: A
WORKING:
Rearrange the equation of line B:
2y - 8x - 9 = 0
2y = 8x + 9
y = 4x + \dfrac{9}{2}
Line A and Line B have the same gradient, so are parallel.
