During a new-year sale, a shopkeeper offers a discount scheme to his customers, ‘Buy 5 Sweaters, Get 2 Sweaters Free’. Find the effective percentage discount given by the shopkeeper.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. %.
For every 5 sweaters bought, the customer gets 2 additional sweaters free
Thus, the customer is receiving 7 sweaters for the price of 5 sweaters
Let the cost price of 1 sweater be Rs.x
So,
Discount = Total cost − Discounted cost
Discount = 7x - 5x = 2x
Discount% = Discount/Original cost × 100
⇒ 2P/7P × 100
⇒ 200/7 = %
