A Man Bought Apples At 10 For ₹ 75 And Sold Them For ₹ 75 Per Dozen. Find His Loss Per Cent.

Given:  A Man Bought Apples At 10 For ₹ 75 And Sold Them For ₹ 75 Per Dozen.

To find: We have to find the loss percent.

Solution: 

The cost price of one apple -

10 apples = Rs 75

1 apple = $\frac{75}{10}$ = 7.5

Cost Price of one apple = Rs 7.5

Selling price of one apple -

12 apples = Rs 75

1 apple = $\frac{75}{12}$ = 6.25

Selling price of one apple = Rs 6.25

Loss = CP - SP

         = 7.5 - 6.25

         = 1.25 .

Loss Percentage = $\frac{loss}{cp} \ \times 100$

                               = $\frac{1.25}{7.5} \ \times 100$

                               = 16.66 % .
