A dishonest shopkeeper defrauds his customers in two ways - by measuring weights incorrectly and by mixing impurities into his products. Although, he professes to sell his product at its cost price. As being deceitful, he uses an incorrect weight which is equal to 80% of the real weight. Further greed overtook him and he added 20% impurities to the product. Find his net profit percentage?

Option 3 : 56.25%

Let, the weight of the product be 100 kilograms and its price be Rs. 100

∴ The cost of 1 kilogram of the product will be Rs. 1

∵ He weighs only 80% of the real weight,

It means he is weighting 80 Kgs instead of 100 Kgs.

∴ The cost price of 80 Kgs of product = Rs. 80

Now,

He adds 20% impurities to the product

∴ Actual product in the 80 kg product sold = 80 x (100 - 20)/100 = 64 kg

Profit = x 100 = x 100

Profit = (36/64) x 100 = 56.25%
