Question

a watch bought for Rs.400 is sold at a profit of 20%.Its S.P. is Rs.









​

Answer 1

• Cost price (CP) = 400
• SP = CP + Profit = 400+ 20XSP /100
• 400 = SP - 20SP/100 = 80SP/100
• SP = 400X100/80 = 500

The selling price is Rs 500

Answer 2

Let S.P = Rs. X

Then, 400 + 20% of x = x

=400 + X/5 = X

=4X/5 = 400

=x = 400 × 5/4 = 500

S.P = Rs. 500

Ans: The S P of the watch is ₹ 500.
