Question

if apples are brought at 11 for rs 10 and sold at 10 for rs 11, how much will be the gain in percentage ?

Answer 1

Cost price of an apple at 11 = rs 10
Cost price of apple at 1 = 10/11
Selling price of an apple at10 = rs 11
Selling price of apple at 1 = 11/ 10
Since
Gain = selling price - cost price
= 11/10 - 10/11 =21/110
Gain percent =
gain×100/ cost price
= 21/110×100 / 10/11 =21%

Answer 2

hope this helps you........
