Question

. A man bought a Laptop for Rs. 45,000 and a TV set for Rs. 20,000. He sold the Laptop at a profit of 6 % but made a loss of 12% on the TV set. Find his profit or loss percent in the whole transaction. ​

Answer 1

Answer:

His profit percent in the whole transaction = 0.46 %

Step-by-step explanation:

Given,

Cost Price ( CP ) of Laptop = Rs 45,000

Profit % on Laptop = 6 %

Cost Price ( CP ) of TV set = Rs 20,000

Loss % on TV set = 12 %

We know that:

Selling Price ( SP ) of Laptop = $\frac{100+ Profit}{100} * CP$

                                               = $\frac{100+6}{100}*45,000$

                                               = Rs 47,700

Selling Price ( SP ) of TV set = $\frac{100- Loss}{100} * CP$

                                                = $\frac{100-12}{100}*20,000$

                                                = Rs 17,600

Now,

Total Cost Price ( CP ) = Rs 45,000 + Rs 20,000

                                    = Rs 65,000

Total Selling Price ( SP ) = Rs 47,700 + Rs 17,600

                                        = Rs 65,300

Here, SP > CP

Therefore, There is Profit.

Profit Percent = $\frac{SP-CP}{CP}*100$

                       = $\frac{65,300-65,000}{65,000}*100$

                       = 0.46 %

Therefore,

His profit percent in the whole transaction = 0.46 %
