Question

Aanand, a shopkeeper earns a profit of 15% after selling an article at 20% discount on the printed price.
Find the ratio of the cost price and the printed price of the article.​

Answer 1

Answer:

Step-by-step explanation:

Profit%=15%

Discount%=20%

CP=?

MP=? x(let)

now,

SP=MP-d% of MP

=x-20/100*x

=80x/100

SP=4x/5

now,

profit%=SP-CP/CP*100%

15%=4x/5-CP/CP*100%

15=4x-5CP*100

0.15=4x-5CP

0.15+5CP/4=x
