Question

A retailer bought 20 kg tea at a discount of 10%. Besides 1 kg
tea was freely offered to him by the wholesaler at the
purchase of 20 kg tea. Now he sells all the tea at the marked
price to a customer. What is profil percentage of retailer?
(a) 30%
(b) 129
(c) 16.66%
(d) none of these

Answer 1

Let the MP 1 kg tea be Rs. 1,

Then CP of 20 kg with discount = 20 x 0.9 = Rs.18

Also 1 kg tea is free. So the retailer gets tea worth Rs. 21 by paying Rs. 18 only.

profit % = ( goods left / goods sold) x 100

= (21-18 / 18 x 100 = 16.66 %
