Question

Gopi sold a laptop at 12% gain if it had been sold for 1200 more, the gain would have been 20%.find the cost price of the laptop

Answer 1

Answer:

cost price of the laptop = Rs 15000

Step-by-step explanation:

Let say Cost Price of Laptop  = C  Rs

12 % Gain  = (12/100)C = 0.12C  Rs

Selling Price = C + 0.12C = 1.12C  Rs

if Sold for Rs 1200 More then

Selling Price = 1.12C + 1200  Rs

Gain = 20 %

= (20/100)C

= 0.2C

Selling Price = C + 0.2C = 1.2C

1.2C =  1.12C + 1200

=> 0.08C = 1200

=> C = 15000

cost price of the laptop = Rs 15000
