Question

If Aju scored $70$ and $85$ in two tests out of $100$, 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 previous paper $=\frac{70}{100}\times 100=70\%$

Percentage of marks in current paper $=\frac{85}{100}\times 100=85\%$

Increase in percentage of marks $=85\%-70\%=15\%$
