There are 1800 gym members in total.

$\frac{3}{4}$ are aged 25-59 years.

$\frac{1}{5}$ are over 60 years old.

The remainder are under 25 years old.

How many members are under 25 years old?

3/4 of 1800 is [tex]\displaystyle{ \frac{3}{4}\cdot1,800 = 3\cdot450=1,350[/tex].

1/5 of 1800 is [tex]\displaystyle{ \frac{1}{5}\cdot1,800 = \frac{1,800}{5}=360[/tex]

Thus, out of 1,800 members, 1,350 are aged 25-59, 360 are aged over 60.

The remaining, 1,800-1,350-360 = 90, are members under 25 years old.

Answer: 90
