Question

By selling an article for Rs. 9,900 , Shashank gains 10%. Find his cost price

Answer 1

Let the cost price of article be Profit or Gain = 10%

Profit=10%of x

=10/100*x

=1/10 x

Cp + Gain = Sp

x/1 +1/10 x =9900

=10x+1/10= 9900

=11 x /10= 9900

=11x=9900*10

x=9900*10/11

x=9000

Hence cost price is 9000
