Answer 1

Answer:1200

Step-by-step explanation:

Consider the cost price to be x.

1st equation

x - (15/100)x = x + (20/100)x    ...15% discount and gain of 20%

2nd equation

x - (25/100)x = x + 120             ....25%discount and a gain of 120Rs

Solving above equations by subtracting we get

(10/100)x = (20/100)x - 120

Solving LHS and RHS..

(10/100)x =120

x=1200
