Question

the loss % on selling 140 geometry boxes when the loss is equal to S.P. of 10 geometry boxes is

Answer 1

Let the SP of 1 geometry box be Rs.1

Then,SP of 10 geometry boxes$=Rs.10$

Then according to question loss on 140 geometry boxes $=Rs.10$

And SP of 140 geometry boxes $=Rs.140$

Hence CP of 140 geometry boxes $=loss+SP=Rs.(10+140)=Rs.150$

Therefore loss%$=\frac{10}{150}\times 100$

$=6.67$%
