Question

an article was sold rs 250 with profit of 5% what is its cost price

Answer 1

let the cost prise = x

S.P = C.P + profit
250 = x + 5% of x
250 = 105x\100
x = 250 × 100 \ 105
x = 238.09

Hence,
cost prise = Rs 238.09

Hope it helps!!

Answer 2

As we know that Profit Rs = Profit%/100 × CP
                     And Profit Rs = SP - CP
        Then, SP - CP = Profit%/100 × CP
Let CP be x
Then,         from ques
             250 - x = 5/100 × x
     100(250 - x) = 5x
    25000 - 100x = 5x
              25000  = 100x + 5x
                 105x = 25000
                       x =  Rs 238.0952380952381
So CP is approximately = Rs 238
