Dinesh purchases 10 dozens of apples at the rate of Rs 180 per dozen. He sold each one of them at the rate of Rs 19.5. What is the profit (in percentage) of Dinesh?
Cost of 1 dozen apples = Rs. 180
=> Cost of 10 dozen apples = $$180\times10=Rs.$$ $$1800$$
=> Cost of 1 apple = $$\frac{1800}{10\times12}=Rs.$$ $$15$$
Selling price of 1 apple = Rs. 19.5
=> Profit % = $$\frac{(19.5-15)}{15}\times100$$
= $$1.5\times20=30\%$$
=> Ans - (A)
