 cp for distributor=0.70x
sp for distributor=0.80x
profit for distributor=0.10x
profit% for the distributor=14.2%

cp for the book seller=0.80x
sp for the book seller=x
profit=0.2x
profit% for the bookseller=25%

Answer 2

Let the printed price be rs 100. Distributor cp= (100-30)% of 100= rs 70. Distributor sp= (100-20)% of 100= rs 80. Profit=sp-cp=rs10. Bookseller cp= rs 80. Bookseller sp= rs 100. Profit = sp-cp=rs 20. Distributor profit% =10/70*100= 14.2%. Bookseller profit%= 20*100/80=25%
