उत्तर
C.P. of 300 eggs @ 80 paise each
= 300 × 80 = 24000 paise = Rs.240
No. of eggs which were broken in transaction = 30
Remaining eggs = 300 − 30
= 270
S.P. of eggs @ Rs.1 each = 270 × 1= Rs.270
Gain = S.P. − C.P.
= Rs.270 − Rs.240 = Rs.30
Gain% =`"Gain"/"C.P."xx100`
`=30/240xx100`
`=100/8%=12.5%`
