Question

A shopkeeper purchased a calculator dor ₹650. he sells it at a discount of 20% and still makes a profit of 20% . find i) the selling price ii) marked price

Answer 1

Sp = profit\cp×100

=20\650×100
=40\3

Answer 2

CP of the calculator = Rs 650

Profit = 20% of Rs 650 = Rs 130

(i) SP of calculator = Rs 650 + Rs 130 = Rs 780 (Ans)

(ii) Let MP of the calculator be x

Discount = 20% of x = x/5

So, x - x/5 = 780

= 5x -x = 780 * 5

= 4x = 3900

= x = 3900 / 4

= x = 975

Therefore MP of the calculator was Rs 975. (Ans)
