• B. Rs.21.25
• C. Rs.18.26
• D. Rs.15.24

Answer 1

The correct option is B Rs.21.25

C.P. of 80 Kg apple =$80\times 12.5=1000$
C.P. of 50Kg Apple=$50\times 12.5=625$
Loss on sell of 50 Kg apple =$\frac{10\times 625}{100}=62.5$
C.P. of 30 Kg apple =$30\times 12.5=375$
Seller want to 20% gain on 80 apple=$\frac{1000\times 120}{100}=1200$
S.P of 30 Kg apple = 1200 - 562.5=637.50
S.P. of one kg apple =$\frac{637.5}{30}=21.25$
