CP of 11 shirts=SP of10 shirts
Let the CP of 1 shirt be Rs. x
CP of 11 shirts = 11x
SP of 10 shirts = 11x
SP of 1 shirt     =11/10x
Profit                =SP-CP
                        =11/10x-x
                        =x/10
                        =Profit/ CP *100
                        =x/10/x*100

Answer 2

Given - Cost price and selling price

Find - Profit percentage

Solution - The profit percentage is 20%.

As per the given information, the cost price of 12 shirts = the selling price of 10 shirts.

Let the cost price of 12 shirts be x.

So, the cost price of 1 shirt = x/12.

The selling price of 10 shirts = x

So, the selling price of 1 shirt = x/10

Calculating profit = selling price - cost price

Profit = x/10 - x/12

Profit = 6x - 5x/60

Profit = x/60

Profit percentage = profit/cost price*100

Profit percentage = x/60/x/12*100

Profit percentage = 12x/60x*100

Profit percentage = 20%

Hence, the profit percentage is 20%.
