comment Why are derivatives specified as d/dx?
@JasonChen you will never find d/dx alone. The top delta corresponds to the function following the d/dx. Eg d/dx sin x . it is delta sin x /delta x.

comment How to solve this Ratio problem
Sorry I typed B instead of D, but the ratio of passengers is 1:50, So if x passengers travel by Ist class , 50x will travel in IInd class.

comment Solving the algebraic equation
I am not clear about how $x^2-40x+400$ becomes $(x-20)(x-20)$.Please explain it too.

comment Solving the algebraic equation
No, I did not give the full equation here .The actual problem is $$x={{(2{(x-10))}}{({({(x-5)}-{(x-10)})}{({({(x-5)}-{({(x-10)}-1})})})}\over x}$$
