Let the total number of employee in marketing = X

therefore, the number of male =0.6x

number of female =0.4x

Let the total number of employee in finance = Y

therefore, the number of male =0.4y

number of female =0.6y

we have to find: 0.4x-0.6y

or 0.6y-0.4x

Statement 10.6x=0.4y

or, 3x =2y

We have 2 variables and one equation , hence insufficient

Statement 2 0.6y =9/4*0.4x

or

3x =2y

same as statement 1, insufficient

combining statement 1 and 2

we have 3x=2y, insufficient

Hence answer is E
