Question

Find cp when ,,a cycle is sold for rs1485 at aprofit of 8 percent

Answer 1

Take CP as x

S.P.= 1485

Profit%= 8

Profit % = Profit/CP *100

8 = (SP-CP)/CP *100

8=1485-x/x*100

8x=(1485-x)100x

8x=148500x-100x^2

100x^2+8x-148500x=0

$\frac{ - (b)\frac{ + }{} \sqrt{b {}^{2} - 4ac } }{2a}$
