Question

by selling an article for rupees 475 Rahul lost 5% find CP of the article

Answer 1

The formula is cp=100/100-loss%*sp so according to formula you will get cp=rp500

Answer 2

Let cost price of an article = Rs 100

Loss = 5% of Rs 100

Loss = Rs 5

Selling price of article = Rs (100 - 5)

Selling price of article = Rs 95

If S.P. of article is Rs 95, then C.P. = Rs 100

If S.P. of article is Rs 1, then C.P. = Rs 100/95

If S.P. of article is Rs 475, then C.P. = Rs (100/95 × 475)

= Rs 500

Note:-

We can also calculate C.P using formula:-

• C.P. = S.P. × [100/100 - Loss%]

• C.P. = S.P. × [100/100 + Gain%]
