Question

A dealer sold two tv sets for ` 2400 each, gaining 20% on one and losing 20% on the other set. find his net gain or net loss.

Answer 1

200 net loss on both tvs

Answer 2

Answer:

Rs.200

Step-by-step explanation:

He sold 1st machine at $2400 at 20% gain

Now, the cost price of 1st machine =$\frac{SP \times 100}{100+gain\%}$ =$\frac{2400 \times 100}{100+20}$ = Rs.2000

Now gain = S.P. -C.P. = 2400-2000= Rs. 400

Then, he sold 2nd machine at 20 % loss

Now, the cost price of 2nd machine =$\frac{SP \times 100}{100-loss\%}$ =$\frac{2400 \times 100}{100-20}$ = Rs.3000

Now his loss = 3000 - 2400 = 600 rs

Now, his net loss = Total Loss - Total Profit =600- 400 = Rs.200

Thus His net loss is Rs.200
