Question

A man bought apples at the rate of 8 for Rs. 34 and sold them at the rate of 12 for Rs. 57. How many apples should be sold to earn net profit of Rs.45?

• A. 90
• B. 100
• C. 135
• D. 150
• E. 160

Answer 1

The correct option is A

90

C.P of 1 apple = Rs. $\frac{34}{8}$ = Rs. 4.25 S.P of 1 apple = Rs. $\frac{57}{12}$ = Rs.4.75

Profit on each apple = Re. 0.50.

$\therefore$ Number of apples required = $\frac{45}{0.50}=90.$
