Question

A man sold an article for Rs 495 and gained 10%on it. Find the cost price of the article.

Answer 1

Given SP = 495 rupees.

          Gain = 10%.

We know that CP = (100 * SP) / (100 + Gain%)

                              = (100 * 495) / (100 + 10)

                              = 49500 / 110

                              = 450.


The cost price of the article = 450 rupees.


Hope this helps! :)

Answer 2

Sp=Rs495

Profit%=10%

Cp=?

Cp= (100/100+p%)×sp
(100/100+10)×495
(100/110)×495
Ans = 450
