Question

Raman sells an article at a loss of 10%. If he had sold it for rs,30 more he would have gained 5%. Find the cost price of the article.

Answer 1

Let CP = x

Sp is 90 % of x (considering 100% value , for ex. If Cp = 100/- Sp= 90/- then loss = 10/-)

If he sold for rs 30/- more, the profit will be 5% or 105%of x.

Now ,

90%x + 30 = 105%x

(90 + 3000)/100 = 105x/100

Cancelling the denominator of 100 we get,

90x + 3000 = 105x

15x = 3000

X = 200/-

or Cp = rs 200/-
