- 24.25%
If CP=x, then SP=1.4x & stock=y, then CP of bookseller=xy
Total SP=[1.4x*(y/2)] + [1.4x*(85/100)*(y/4)] + [1.4x*(70/100)*(y/4)]
=0.7xy+ 0.2975xy + 0.245xy=1.2425xy
Gain %=100*(1.2425xy -xy)=24.25 - 8 years agoHelpfull: Yes(0) No(0)
- ans is 24.5%
let 100 books
cp=x
50(140x)/100+25(119x)/100+25(98x)/100
(280x+119x+98x)25/100
497x/4
124.5x this is total gain - 8 years agoHelpfull: Yes(0) No(0)
