GIVEN
Eclairs were bought at 11 for Rs 10 and sold at 10 for Rs 11.
TO FIND
The gain or loss per cent.
SOLUTION
We can simply solve the above problem as follows;
It is given,
Cost price of 11 eclairs = Rs 10
Cost price for 1 eclair = Rs 10/11
Cost prive for 10 eclairs = 10/11 × 10 = Rs 9
Now,
It is given that 10 eclairs were sold for Rs 11
Therefore,
Selling price of 10 eclairs = Rs 11
We can observe that Selling price is greater than cost price so
Profit = Selling price - Cost price
= 11 - 9 = Rs 2
Profit% = (Profit/Cost price)× 100
= (2/9)× 100
= 22.2%
Hence, The profit percentage is 22.2%
