Problem-Solving and Data Analysis practice question

Answer: 200

Each dollar is 0.80 euros, so 250 dollars are 250 × 0.80 = 200 euros.

Common wrong answers

If you answered 20

20 is 250 × 0.08, a misplaced decimal.

If you answered 2000

2,000 is 250 × 8, treating 0.80 as 8.

If you answered 312.5

312.5 is 250/0.80, converting in the wrong direction (that would be dollars from 250 euros).
