Answer 2

Answer:

TV price = 20000

Fridge price = 10000

Step-by-step explanation:

Let t be the cost price of the TV and f the cost price of the fridge.

5% gain on TV and 10% gain on fridge = gain of 2000

=> 5% of t  +  10% of f  =  2000

=> 0.05 t  +  0.1 f  =  2000

=> t + 2f = 40000   ... (1)

10% gain on TV and 5% loss on fridge = gain of 1500

=> 0.1 t - 0.05 f  =  1500

=> 2t - f = 30000   ... (2)

=> 4t - 2f = 60000   ... (3)               [ double previous equation ready to eliminate f in equation (1) ]

Adding equations (1) and (3) gives:

5t = 100000  => t = 20000

Using equation (2) gives

f = 2t - 30000 = 40000 - 30000

=> f = 10000
