Question

an article was sold for rupees 250 with a profit of 5% what is its cost price

Answer 1

Selling Price in Percentage:

Profit = 5%

Selling Price = 100 + 5 = 105%

Find the cost price:

Selling Price = 105%

Selling Price = Rs 250

105% = 250

1% = 250 ÷ 105 = 50/21

100% = 50/21 x 100 = Rs 238

Answer: The cost price is Rs 238

Answer 2

selling price  =  250    

profit %        =   5

profit %         =  s p - c p  x  100

                             c p

 5             =    (250 - c p) /c p   x  100

 5 c p       =    (250 - c p) x 100

5 c p        =  25000 - 100 c p

5 c p + 100 c p   =  25000

     105 c p         =  25000

       cost price   =  25000 / 105

                            =  rs.  238.10
