Question 39

The loss per cent on selling 140 geometry boxes at the loss of SP of 10 geometry boxes is equal to ___.

Answer 1

Let the selling price of 1 geometry box be Rs 1.
So, the selling price for 140 geometry boxes = Rs 1 $\times$ 140 = Rs 140
Similarly, selling price of 10 geometry boxes = Rs 1 $\times$ 10 = Rs 10

Loss= C.P - S.P

10= C.P - 140

C.P = 150
$\because$ Loss = Selling price of 10 geometry boxes = Rs 10
$\therefore$ Loss percentage =$=\frac{Loss}{CP}\times 100=\frac{10}{140+10}\times 100=\frac{10}{150}\times 100=\frac{20}{3}\%=6\frac{2}{3}\%$
