Find the single discount which is equivalent to successive discounts of 20%, 15% and 10%.

A.	38.8%	B.	61.2%
C.	30%	D.	51.8%

Answer and Explanation

Answer:38.8%

Explanation:
Let marked Price = Rs. 100
1st discount = 100 × 20 /100 = Rs. 20
2nd discount = (100 – 20) × 15 / 100 = 80 × 15 /100 = Rs. 12
3rd discount = (80 – 12) × 10/100 = 68/10 = Rs. 6.8
Single discount = Sum of all the discounts = 20 + 12 + 6.8 = 38.8%
