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
