Answer:
"The answer to this question is 18 kg. The explanation is given below.
We can take the weight of sold item as W kg
We can take the cost of item as C per kg
Let say weight of item sold = W kg
The loss percentage is 10%
Loss = (10/100) C = 0.1C Rs
Selling cost = C - 0.1C = 0.9C Rs
0.9C = 40
0.1C = 40/9
Loss per kg = Rs 40/9
Loss for W kg = 40W/9
40W/9 = 80
W = 18 kg
