A customer was offered a discount of 40% on a piece of cloth. On insisting further, the shopkeeper agreed to a further discount of 20% on above. What was the effective discount offered to the customer?
Answer & explanation
Correct answer: option 3
First discount = 40%
Second discount = 20%
Then,
Successive discount = x + y - \(\frac{x × y}{100}\)
Successive discount = 40 + 20 - \(\frac{40 × 20}{100}\) = 52%
