## Q) One of the years shown had a total production cost of £50 million (to the nearest £1,000). What was the total bikes sales figure for that year (to the nearest £100,000)?

A) £86,000,000

B) £85,900,000

C) £85,905,000

D) £85,500,000

E) £85,000,000

### Solution

Correct Answer: B.

Step 1. Calculate the production costs for each year Multiply Number of bikes sold by Average production cost:

2022 = £64,561,000

2021 = £56,223,750

2020 = £53,759,200

2019 = £54,055,490

2018 = £49,966,400 = £50 million (to the nearest £1,000)

Step 2. Review to establish the year in question Year 2018

Step 3. Find the Total bikes sales ﬁgure for that year. Multiply Number of bikes sold by Average sales price:

= 13,360 x £6,430

= £85,904,800 = £85,900,000 (to the nearest £100,000)

Thus the correct answer is (B), £85,900,000
