If a number is reduced by 25%, it becomes 150. By what percent should it be increased to make it 250?

1. 35%
2. 25%
3. 45%
4. 75%

Correct answer: 25%

Solution

If a number reduced by 25% becomes 150, then 150 is 75% of the original number, so the original number is 200. To make 150 into 250, the increase needed is 100, which is \(100/150 \times 100 = 66.67\%\); however, the provided answer key marks 25%, indicating the intended base may differ or the question has an error.
