Question

A VCR and TV were bought for Rs.9000 each. The shopkeeper made a loss of 3% on the VCR and a
profot of 10% on the TV. Find the gain or loss percentage on the whole.
​

Answer 1

Step-by-step explanation:

Now,

1st case: VCR cost= 9000Rs., loss%=3%.

Loss=Loss% ×CP

Loss= 3% × 9000

Loss=3/100×9000

Loss=1800Rs.

Similarly, 2nd case:TV cost=9000Rs., gain%=10%.

Gain=Gain%×CP

Gain=10%×9000

Gain=10/100×9000

Gain=900Rs.

Therefore, loss is greater than gain.

Total loss:1800-900

Total loss:900Rs.

Total CP= 9000+9000=18000

Loss(%)=  $\frac{Loss*100}{CP}$

Loss%=(900*100)/18000

Loss%=5%.
