Question

12%profit on the computer is RS 540 then what is the cost price and sale price of a computer

Answer 1

Answer:

The cost price is Rs. 4500 and the sale price is Rs. 5040.

Step-by-step explanation:

Let the cost price of the compute be Rs. x.

The profit earned is, Rs. 540.

The profit percentage is, 12%.

The formula to compute profit is:

Profit = SP - CP

$540=x[1+\frac{12}{100}]-x\\540=1.12x-x\\540=0.12x\\x=\frac{540}{0.12}\\x=4500$

Compute the selling price as follows:

SP = CP + profit

     = 4500 + 540

     = 5040

Thus, the cost price is Rs. 4500 and the sale price is Rs. 5040.

Answer 2

Step-by-step explanation:

profit=sp-cp

1+p%/100=sp/cp

sp=cp(1+p%/100)

p=cp(1+p%/100)-cp

let Cp is x

540=x(1+12/100)-x

540=x+0.12x-x

540=0.12x

x=540/0.12

x=4500 , x is Cp =4500

p=sp-cp

540=sp-4500

sp=540+4500

sp=5040
