[1]

(b)(i)

Write down all the multiples of 4 between 21 and 29.

[1]

(b)(ii)

Write down a common multiple of 4 and 6.

[1]

(c)

Jenny uses her data to estimate the probability of the spinner landing on each colour.

(a)

Write down Jenny’s estimate for the probability of landing on red.

[1]

(b)

Jenny then writes in some of the colours on this probability scale.

Figure for question 7
(b)(i)

Write the correct colour in the box.

[1]

(b)(ii)

Explain why Jenny’s estimate for the probability of landing on yellow cannot be the actual probability.

Question 9

Tom buys a radio for £40. Later he sells it and makes a profit of 20%.

Tom says

The ratio of the price I paid for the radio to the price I sold the radio is 5: 6.

Show that Tom is correct.

........

[2]

(b)

Find the probability that Ryan

(b)(i)

misses the target and does not score a goal,

[2]

(b)(ii)

either hits the target or scores a goal or both.

Question 17

Two model cars, A and B, are in a race. They start together on the starting line. Assume each car travels at a constant speed.

Car A takes 30 seconds to complete each lap of the track. Car B takes a whole number of seconds to complete each lap of the track. The two cars next cross the starting line together 150 seconds after the start of the race.

Find the four possible times that car B could take to complete one lap.

Question 18

(a)

Write down the multiplier for an increase of 140%. Give your answer as a decimal.

[1]

(b)

Ali invests £1500 in October. The investment increases in value by 10% in November. It then decreases in value by 20% in December.

Ali says

10% – 20% = - 10%, so the £1500 has lost exactly 10% of its value.

(b)(i)

Explain what Ali has done wrong.

[1]

(b)(ii)

Work out the correct percentage loss.

Question 22

The diagram shows two rectangles, A and B.

Figure for question 22

Rectangle A has a width of 25 cm and a height of 12 cm. The width of rectangle B is three times the height of rectangle B.

The area of rectangle A is equal to the area of rectangle B.

Find the perimeter of rectangle B.

[5]

Question 23

Kay invests £1500 in an account paying 3% compound interest per year. Neil invests £1500 in an account paying r % simple interest per year.

At the end of the 5th year, Kay and Neil’s accounts both contain the same amount of money.

Calculate r. Give your answer correct to 1 decimal place.
