Question 93

By selling 15 items, a seller recovers the cost price of 20 items. Then his profit percent is

Solution

A/q

20 C.P. = 15 S.P.

15 C.P. + 5 C.P. = 15 S.P.

5 C.P. = 15 S.P. - 15 C.P.

C.P = $$\frac{15}{5}$$ (S.P. - C.P.) = 3 (S.P. - C.P.)

C.P = 3 (S.P. - C.P.)

$$\frac{1}{3}$$ = $$\frac{(S.P. - C.P.)}{CP}$$ = Fractional Profit

Profit percentage = Fractional Profit x 100 = $$\frac{100}{3}$$ %

=33$$\frac{1}{3}$$ % Answer
