Question

a man buys 10eggs for 15rupees & sells 20eggs for 16rupees. Then what is the loss percent?

Answer 1

loss percentage 0.7/0.8
=7/8

Answer 2

C.P of 10 eggs = 15
C.P of 1 egg = 15/10
S.P of 20 eggs = 16
S.P of 1 egg = 16/20 = 8/10
Loss = C.P - S.P
=15/10 - 8/10
= 7/10
Loss % = (Loss/C.P) × 100
= (7/10)/(15/10) × 100
= (7/15) × 100
= 140/3
= $46 \frac{2}{3} \%$
