Answer 2

Therefore the percentage gain is 21 %.

If 11 eggs are bought for Rs. 10 and 10 eggs are sold for Rs. 11.

We have to find the percentage gain or loss.

∵ 11 eggs are bought for Rs. 10.

∴ cost price of each egg , CP= total cost/number of eggs bought

= Rs. 10/11

∵ 10 eggs are sold for Rs. 11.

∴ selling price of each egg , SP = total amount/number of egg sold

= Rs. 11/10

we see, 11/10 > 10/11

i.e., SP > CP hence shopkeeper gets profit.

now percentage profit (or gain) = (SP - CP)/CP × 100

$=\frac{\frac{11}{10}-\frac{10}{11}}{\frac{10}{11}}\times100$

$=\frac{121-100}{110\times\frac{10}{11}}\times100$

= 21 %

Therefore the percentage gain is 21 %.
