Answer:

Step-by-step explanation:

Answer:

The cost price of the laptop is Rs15000

Step-by-step explanation:

Let the cost price of the laptop be Rs X.

If gain is 12% then selling price = X+(12/100) X = 1.12X

If gain is 20% then selling price is = X+(20/100) X = 1.2X

Now according to question,

1.2X-1.12X =1200

0.08X = 1200

X = 1200/0.08 = Rs 15000

Thus the cost price of the laptop is Rs 15000.
