Solution

Share

Let the cost price be Rs. 1000 per kg

So, Selling price = Rs. 900 per kg

But he sells only 70% of the quantity claiming it to be 100% quanitity.

So, the actual cost price of 700 grams = Rs. 700

Actual selling price = Rs. 900

Profit = Rs. 200

Profit % = (Profit/Cost Price)*100 = 200/700 = 200/7 % = $$28\dfrac{4}{7}$$%
