The loss per cent on selling 140
Question:

The loss per cent on selling 140 geometry boxes at the loss of S.P. of 10 geometry boxes is equal to _____

Solution:

20/3%

Explanation: Say, the selling price of one geometry box = Rs.1

So, the selling price of 140 geometry boxes = 1 × 140 = Rs.140

Selling price of 10 geometry boxes = Rs.10

Loss = Rs. 10

Loss percentage = Loss/CP × 100

= 10/(140+10) × 100

= 10/150 × 100

= 20/3%
