Question

A shopkeper sold an article at a gain of 5% . if he had sold it for rupees 16.50 less, he would have lost 5% . find the cost price of the article.

Answer 1

Cost price = a

Original SP = 105/100

Selling price if he has sold for less price = 105a/100 - 16.50

(105a/100 - 16.50)a  x 100 = 95

95a = 105a - 1650

10a = 1650

a = 165

Cost Price = Rs. 165
