Question

25.A fruit seller bought 600 bananas at Rs.16 a dozen. He sold 200 of

them at 4 for Rs.5 and the remaining at 2 for Rs.3. Find gain or loss
percent.

Answer 1

The 600 bananas cost 600/12 = 50 dozens * Rs. 16/dozen = Rs. 800.
He sold 200 bananas at 4 for Rs.5, so each banana cost Rs.5/4 = Rs. 1.25.
He sold the remaining 400 bananas at 2 for Rs.3, so each banana cost Rs.3/2 = Rs. 1.50.
He earned Rs. 200*1.25 + 400*1.5 = Rs. 250 + Rs. 600 = Rs. 850 from selling the bananas.
His gain or loss is (850-800)/800 *100 = 6.25%. So, the gain percentage is 6.25%.
