Question

Mani sold an article for Rs 531 and gained 18% on it. Find the cost price of the article.

Answer 1

Let the cost price be Rs a

Selling price = Cost price + Gain

=> 531 = a + 18a/100

=> 531 = 118a/100

=> a = 53100 / 118

=> a = 450

Cost price = Rs 450

Answer 2

Let the cost price be Rs a

Selling price = Cost price + Gain

=> 531 = a + 18a/100

=> 531 = 118a/100

=> a = 53100 / 118

=> a = 450

Cost price = Rs 450
