A man makes a profit of 20% after selling a product on 28% discount on the printed price. Find the ratio of printed price to cost price.
Answer & explanation
Correct answer: option 2
Profit (P)% = 20%
S.P. = C.P. × 120% ..........(i)
Discount (D)% = 28%
S.P. = M.P. × 72% ...........(ii)
S.P. in both cases is equal, (i) = (ii):
⇒ C.P. × 120% = M.P. × 72%
⇒ C.P. × 5 = M.P. × 3
⇒ M.P. : C.P. = 5 : 3
