There are 4680 gym members in total. 3/8 are aged 25-59 years, 2/5 are over 60 years and the remainder are under 25 years. How many members are under 25 years?

Respuesta :

9/40 of the members are under 25 years.

Answer:

1053 members under 25 years.

Step-by-step explanation:

We have been given the total number of students: 4680

[tex]\frac{3}{8}\text{aged}25-59[/tex]

That means in 25-59 there will be:

[tex]4680\cdot\frac{3}{8}=1755[/tex]

And [tex]\frac{2}{5}\text{are over}60\text{years}[/tex]

That means over 60 years will be:

[tex]4680\cdot\frac{2}{5}=1872[/tex]

That means from total 1755+1872=3627

That means 4680-3627=1053 are remaining

And hence, 1053 members are under 25 years.
