By selling an article for Rs 1,12,000 a girl gains 40%. The cost price of the article was ______.

#### Solution

By selling an article for Rs 1,12,000 a girl gains 40%. The cost price of the article was ₹ 80000.

Explanation:

Selling price of an article = ₹ 112000

Gain% = 40%

Let x be the cost price of the article.

∴ Cost price = selling price – profit % on cost price

∴ Selling price = cost price + profit % on cost price

So, 112000 = x + x xx 40/100

⇒ 112000 = (100x + 40x)/100

⇒ 112000 × 100 = 140x

⇒ x = (112000 xx 100)/140

⇒ x = (112000 xx 5)/7

⇒ x = 16000 × 5

⇒ x = ₹ 80000
