Answer 1

heya..........



To solve these questions, you can form simultaneous equations:

First let price of t.v be x  and that of the fridge be y

5% gain on chair= 5/100x= 0.05x

10%gain on fridge= 10/100y =0.1y

Therefore 0.05x + 0.1 y = 2000(total profit).....first equation(hence 5x+10y=200000)


10%gain on t.v = 10/100x =0.1x

5%loss on fridge= -5/100y =-0.05y


Therefore 0.1x - 0.05y = 1500......our second equation (hence, 5y= 10x-150000...y = (10x-150000)/5....y=2x-30000


solve by substitution: y= 2x-30000

5x+10y=200000

5x + 10(2x-30000)=200000 

5x + 20x -300000= 200000

25x = 500000

   x=  20000

y= 2x-30000

  =2(20000)-30000 

  =40000-30000

 y =10000


 the price of the tv = Rs. 20,000

   price of the fridge= Rs. 10,000

For calculation, see the attachment.

The current cost price of 
T.V = Rs. 20,000 and
Fridge = Rs. 10,000
