Question

The price of a laptop is fixed 20% above it's cost price and sold it at 13% discount to gain Rs. 1980.how much should a costumer pay for it. ​

Answer 1

Step-by-step explanation:

let cp be 100x

now mp is 120x

so sp is 120x87/100 = 104.4x

thus gain is sp-cp = 4.4x

4.4x = 1980

x = 450

so cp= 45000

and sp = 46980

so customer should pay ₹46980

PS we can solve it by taking cp as x instead of 100x but decimal will give trouble while solving question.
