Question

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

Answer 1

Answer:

the answer is 330

Step-by-step explanation:

considering the cost of the article as x,

x-16.5 = x-(5% of x)

x-16.5 = x-(x/20)

x-16.5 = 19x/20

20(x-16.5) = 19x

20x-330 = 19x

20x-19x = 330

x = 330

therefore the cost price of the article is 330
