Question

If Aju scored 70 and 85 out of 100 in two consecutive tests, what is the percentage increase in marks scored by him?

• A. 10%
• B. 15%
• C. 20%
• D. 25%

Answer 1

The correct option is B

15%

Percentage of marks in the first test = $\frac{70}{100}\times 100$ = 70%

Percentage of marks in second test = $\frac{85}{100}\times 100$ = 85%

Increase = 85% - 70% = 15%
