Question

11 oranges are bought for 10 and 10 oranges are sold for 11. Find the gain or loss​

Answer 1

Cp of 11 oranges is Rs. 10

So, Cp of 1 orange is 10/11 = Rs. 0.909

Sp of 10 oranges is Rs. 11

So, Sp of 1 orange is 11/10 = Rs 1.1

Profit = Sp - Cp

= 1.1 - 0.909

= Rs. 0.191

Profit / Gain %= profit / Cp × 100

= 0.191/0.909 ×100

=0.210×100

=021.00%

i.e. 21% is his gain percent
