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 a net profit of Rs 45?

• A. 90
• B. 100
• C. 135
• D. 150

Answer 1

The correct option is A 90

Buying price per Apple=34/8=17/4 Rs
Selling price per Apple=57/12=19/4Rs
Profit per apple=Selling price-Buying price
$Profit=\frac{19}{4}-\frac{17}{4}$
$Profit=\frac{2}{4}$
$Profit=\frac{1}{2}$
apples should be sold to earn a net profit of Rs 45
$45=x\times \frac{1}{2}$
$x=2\times 45=90$
Answer (A) 90
