Problem-Solving and Data Analysis practice question
A prize of $840 is shared among three people in the ratio 2 : 3 : 7. How many dollars does the person with the largest share receive?
Answer: 490
The ratio has 2 + 3 + 7 = 12 parts, so each part is 840 / 12 = $70. The largest share is 7 parts: 7 × 70 = $490.
Common wrong answers
- If you answered 70
- 70 is the value of ONE part. The largest share is 7 parts.
- If you answered 120
- 120 is 840 / 7, dividing by the largest ratio number instead of by the total of 12 parts.
- If you answered 210
- 210 is 3 parts (3 × 70), the middle share, not the largest.
