Question

There are 1800 gym members in total 3/4 are aged 25-59 years 1/5 are over 60 years and the remainder are under 25. How many members are under 25

Answer 1

given. total members =1800

3/4 of total members are between 25 -59

so total members between 25 to 59

=3/4×1800

=1350

:1/5 members are over 60

so members over 60

=1/5×1800

and the remained members are under 25

members remained=1800-(1350+360)

=1800-1710

=90

so total members under 25 are 90

Answer 2

Answer:

3/4=0.75*100=75%

1/5=0.2*100=20%

75%+20%=95%

Remainder 5%

Now

1800×95=171000 ÷100=1710

95% =1710.

1800-1710=90 (5%)

Answer is 90
