The loss per cent on selling 140 geometry boxes at the loss of S.P. of 10 geometry boxes is equal to ______.
उत्तर
The loss per cent on selling 140 geometry boxes at the loss of S.P. of 10 geometry boxes is equal to `underlinebb(6 2/3 %)`.
Explanation:
Let the selling price of 1 geometry box be Rs. 1.
So, the selling price for 140 geometry boxes = Rs. 1 × 140 = Rs. 140
Similarly, selling price of 10 geometry boxes = Rs. 1 × 10 = Rs. 10
Loss = Selling price of 10 geometry boxes = Rs. 10
∴ Loss percentage = `"Loss"/"CP" xx 100`
= `10/(140 + 10) xx 100`
= `10/150 xx 100`
= `20/3`%
= `6 2/3`%
