Question

How much percent more than the cp should a manufacturer mark his goods so that after allowing a discount of 20% on the market price he gains 10%?

Answer 1

Answer:

y=37.5%

Step-by-step explanation:

let CP=100x

let marked price is y % More

then MP=100x+xy

discount=20%

SP=(100x+xy)*0.8

Profit=10%

so (SP-CP)*100/CP

{(100x+xy)*0.8}-100x ]*100/(100x)=10

10x=80x+0.8xy-100x

0.8xy-30x=0

y=30x/0.8

y=37.5%
