Selling Price of bycicle = Rs 75
Cost Price = Rs x
Profit %= x%
Therefore total profit = ( x/100*x) Rs
= x^2 /100 Rs
Profit = S.P - C.P
Or, x^2/100=75-x
Or x^2=7500-100x
Or, x^2+100x-7500=0
Or x^2+150x-50x-7500=0
Or x(x +150)-50(x +150)=0
Or( x-50)(x+150)=0
Or x =50( Amount of money cannot be negative so positive value is taken)
Ans x=50

I hope this helps
