Answer:

1053 members under 25 years.

Explanation:

We have been given the total number of students: 4680

$(3)/(8)\text{aged}25-59$

That means in 25-59 there will be:

$4680\cdot(3)/(8)=1755$

And
$(2)/(5)\text{are over}60\text{years}$

That means over 60 years will be:

$4680\cdot(2)/(5)=1872$

That means from total 1755+1872=3627

That means 4680-3627=1053 are remaining

And hence, 1053 members are under 25 years.
