Answer 1

Given:

Bidhan loses 10 % by selling an article for Rs 900.

To Find:

The profit % he would have made and the cost price of the article.

Solution:

Let CP = 100

Loss = 10% (given)

So, SP = CP - Loss = (100 - 10) = 90

When SP = 90, CP =100

Now when SP = 900, CP = (100/90) x 900 = 1000

So, the cost price of the article is Rs 1000

To determine the profit percent when SP = 1100:-

CP = 1000

SP = 1100

Profit    = SP - CP = (1100 - 1000) = 100

Profit % = (Profit / CP) x 100

            = (100/1000) x 100

            = 10%

Hence, the profit percent when SP = 1100 is 10%
