By selling 39 articles, a person gets the profit equal to selling price of 9 articles. Find profit percent
Answer & explanation
Correct answer: option 1
Profit = S.P. - C.P.
ATQ,
⇒ S.P. of 9 = S.P. of 39 - C.P. of 39
⇒ C.P. of 39 = S.P. of 30
⇒ C.P. : S.P. = 10 : 13
Profit = 3R
Profit percent = \(\frac{3}{10}\) × 100 = 30%
