I did not understand the question especially "2/9 of the men are over 50 years old. If 4 men in the club are over 50 years old" are the both details given correct ?

Hi..

What it means is ...
Let the total men be m, so $$\frac{2}{9}$$m=4, so m=18..
Now 3/8 of x are men, so $$\frac{3}{8}$$x=18...

x=18*8/3=48..
So total is 48

A
