Verified Answer
A shopkeeper first allows a discount of 25% on a certain variety of cl...
GIVEN:
Two successive Discounts = 25% and 20%
FORMULA USED:
Discount % = (Discount/MP) × 100
CALCULATION:
Let M.P = Rs. 100
Total discounted price after allowing two discounts = Rs. 100 × 75/100 × 80/100 = Rs. 60
⇒ Total discount = Rs. 100 – 60 = Rs 40
∴ Required discount % = 40/100 × 100 = 40%
ALTERNATE METHOD:
Net discount after two successive discounts of a% & b% = a + b – ab/100
= 25 + 20 – (25 × 20)/100 = 45 – 5 = 40%
