Answer:

There is neither loss nor profit .

Step-by-step explanation:

C.P of T.V. = Rs. 12000

C.P of VCP = Rs. 12000

C.P of T.V. and VCP = Rs. 24000

T.V. was sold at a loss of 20% .

Therefore, S.P of T.V. = (1 - r/100) X C.P

= (1 - 20/100) X Rs. 12000

= 80/100 X Rs. 12000

= Rs. 9600

S.P of T.V. = Rs. 9600

VCP was sold at a profit of 20% .

Therefore, S.P of VCP = (1 + r/100) X C.P

= (1 + 20/100) X Rs. 12000

= 120/100 X Rs. 12000

= Rs. 14400

S.P of VCP = Rs. 14400

C.P of T.V. and VCP = Rs. 24000

S.P of T.V. and VCP = Rs. 14400 + Rs. 9600

S.P of T.V. and VCP = Rs. 24000

Since, C.P = S.P

Therefore, there is neither loss nor profit.

Step-by-step explanation:

Sp of tv = 12000

Sp of vcr = 12000

20% = 20/100 = 1/5

For loss in tv

Cp. Sp

5. 4

4 => = 12000

Cp of tv = 5 => 12000*5/4 = 15000

For profit in vcr

Cp. Sp

5. 6

6 => 12000

Cp of vcr = 5 => 12000*5/6 = 10000

Total cp = 15000 + 10000 = 25000

Total sp = 12000 + 12000 = 24000

Loss % = (25000-24000)/25000 × 100 = 1000/250 = 4 %

ALTERNATE METHOD

Calculate effective rate of -20% and 20%

Eff. rate = -20 + 20 + (-20)*20/100 = 0 - 400/100

= - 4%

Negative sign indicates loss
