By selling 3 dozen ball pens, a shopkeeper earned the profit equal to the selling price of 10 ball pens. Find his profit percent.
Answer & explanation
Correct answer: option 2
ATQ,
⇒ S.P. - C.P. = Profit
⇒ 36 S.P. - 36 C.P. = 10 S.P.
⇒ 26 S.P. = 36 C.P.
⇒ S.P. : C.P. = 36 : 26, 18 : 13
⇒ Profit = 5R
⇒ Profit % = \(\frac{5}{13}\) × 100 = 38\(\frac{6}{13}\)%
