On selling a boat for rs 521 a man gains 8 %; for how much should he sell it to gain 9%

Answers (1)

Selling Price = 521

Gain percentage = 8%

(S.P. - C.P.)/C.P. =  8/100

S.P. /C.P. -1 =  8/100

521/C.P.  =  108/100

C.P = 482.40

Now Gain percentage = 9%

(S.P. - C.P.)/C.P. =  9/100

S.P. /C.P. -1 =  9/100

S.P./482.40 = 109/100

S.P. = 525.82
