Show the answer and the worked solution
Correct answer: B. 475
Worked solution
- Remaining units = 12,000 − 6,300 = 5,700.
- Remaining days = 30 − 18 = 12.
- Required average = 5,700 / 12 = 475 units per day.
Answer: 475.
The idea
Work with what is left, not with what was done. Remaining work ÷ remaining time is the whole of this question type.
Shortcut. Estimate from 500 a day: 12 × 500 = 6,000 is 300 more than the 5,700 needed, and 300 ÷ 12 = 25, so the rate is 500 − 25 = 475.
Common trap. 525 comes from dividing the 6,300 already produced by the 12 days left (6,300 ÷ 12) instead of the 5,700 still to make.
