Solve the differential equation : $(x+2y^2) \large\frac{dy}{dx}$$=y$, given that when $x=2$ and $y=1$. If x devotes the percentage of who are intelligent and y denotes the percentage of people who are work holic, find x when $y=2 \%$ workoholics are always preferable. Do you agree ?

Question

$\begin{array}{1 1} x=2y^2 \\ x=y^2 \\ x=5y^2 \\ x= 5y^2 \end{array} $
