Question 84

If 1 dupatta is offered free on purchase of 4 dupattas priced Rs 1300 each what is the effective discount on each dupatta?

Solution

Cost price of 1 dupatta = Rs. 1300

Cost price of 5 dupattas = $$5 \times 1300 = Rs. 6,500$$

If 1 dupatta is offered free on purchase of 4 dupattas, => Cost of 4 dupattas = $$4 \times 1300 = Rs. 5200$$

=> Effective discount = $$\frac{6500 - 5200}{6500} \times 100$$

= $$\frac{1300}{65} = \frac{100}{5} = 20\%$$

=> Ans - (B)
