Answer 2

Answer:

His loss per cent in the whole transaction is 1%

Step-by-step explanation:

Case of first jeans

SP of jeans = Rs.990

Gain% = 10%

$CP = \frac{SP \times 100}{100+P\%}$

$CP = \frac{990 \times 100}{100+10}$

$CP =900$

Case of second jeans

SP of jeans = Rs.990

Loss% = 10%

$CP = \frac{SP \times 100}{100-L\%}$

$CP = \frac{990 \times 100}{100-10}$

$CP =1100$

So, Total CP = Rs.900+Rs.1100=Rs.2000

Total SP = Rs.990+Rs.990=Rs.1980

Since SP<CP

So, Loss

Loss = CP-SP = Rs.2000-Rs.1980=Rs.20

Loss% = $\frac{Loss}{CP} \times 100$

Loss% = $\frac{20}{2000} \times 100$

Loss% = $1\%$

Hence his loss per cent in the whole transaction is 1%
