Question

A supplier supplies cartridges to a news paper publishing house. He earns a profit of 25% by selling cartridges for Rs. 1540. Find the cost price of the Cartridges ?

Answer 1

Answer: The cost price of the Cartridges is 1232.

Step-by-step explanation:

Given that,

Profit= 25%

Selling price of Cartridge= 1540

Let the cost price of Cartridge be x.

Profit= 25% of x= 0.25*x

We know

Profit= selling price-cost price

Putting the values in the above equation, we get:

0.25*x= 1540-x

0.25*x+x= 1540

1.25*x= 1540

x= 1540/1.25

x= 1232

Answer 2

Let Cost Price(C.P) = P

gain% = {(S.P-C.P)/C.P} x 100

25 = {(1540-P)/P} x 100

25/100 = (1540-P)/P

=> P = 4(1540)-4P

=> 5P = 4(1540)

=> P = 1232

So, Cost Price = Rs. 1232
