In a scheme, a shopkeeper offers a 10% discount if you buy two or more books. Kiran buys two books for ₹540. If the shopkeeper still makes a 20% profit, find the profit he would make had he sold the books without the discount.

Show answer & explanation

Correct answer: B

Explanation

Selling Price = Cost Price × (1 + Profit/100)
540=CP×(1+20100)540=CP×1.2CP=5401.2=450540 = CP \times \left(1 + \frac{20}{100}\right) \\ 540 = CP \times 1.2 \\ CP = \frac{540}{1.2} = 450
Selling Price (without discount)
540 = 90%
100% =(54090)×100=600= \left( \frac{540}{90} \right) \times 100 = 600
Profit (without discount) = 600 − 450 = 150
Profit without discount = ₹150
