- Question 1 of 50
##### 1. Question

Mahesh marks an article 15% above the cost price of Rs. 540. What must be his discount percentage if he sells it at Rs. 496.80?

CorrectCP = Rs. 540, MP = 540 + 15% of 540 = Rs. 621

SP = Rs. 496.80, Discount = 621 – 496.80 = 124.20

Discount % = 124.2/621 * 100 = 20%IncorrectCP = Rs. 540, MP = 540 + 15% of 540 = Rs. 621

SP = Rs. 496.80, Discount = 621 – 496.80 = 124.20

Discount % = 124.2/621 * 100 = 20% - Question 2 of 50
