A man sold an article for ₹ 396 and gained 10% on it. Find the cost price of the article

###### Advertisements

#### Solution

S.P. of article = ₹ 396

Gain = 10%

Let cost price = ₹ x

∴ S.P. = `("x" xx (100 + 10))/100 = 110/100 "x"`

`therefore 110/100 "x" = 396`

`=> "x" = (396 xx 100)/110 = 360`

Cost price of an article = ₹ 360
