My Explanation to Answer [spoiler]{C}[/spoiler]

40*17 + x + y + z = 43*20 --> this equation will make all the other employees maximum.. and will deduce the lowest age for last three.. (keeping 40 in mind)

So, x + y + z = 180

and if maximum age is 60.. then x is surely above 40.

If we consider the ages less than 40 for other people than the weight on "x+y+z" will increase.. so that will also result in age greater than 40.

And, if we consider ages of other people more than 40 than we are already answering the question.

hence. {C}
