cts - a shopkeper sold 2 items at rs2399880 each such that one is sold at a profit of 40 and another one at a loss of 40 then what is the net loss - skillgun

Selling price of 1st one = Rs.23998.80
Profit = 40% "if there is a profit of R% then Cost price = [SP /(100 + R)] x 100 and in case of loss of R%, CP = [SP / 100 - R] x 100
Here, Cost price of 1st item = 23998.80 x 100 / 140 = Rs.17,142
Selling price of 2nd item = Rs.23998.80
Here loss = 40%
Then cost price of 2nd item = Rs.23998.80/(100-40) x 100 = Rs.23998.80 x 100/60
= Rs.39,998
Total cost price = Rs.17,142 + Rs.39,998 = Rs.57140
Total Selling price = Rs.47997.60
Net loss = Rs.57140 - Rs.47997.60 = Rs.9142.40
