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 years. How many members are under 25 years?

Answer 1

90

Explanation:

3/4 Aged 25-59 = 1800x3/4= 1350

1/5 Over 60 = 1800/5=360

Rest Under 25 = 1800-360-1350= 90

Answer 2

34 +15= 49
1800-49= 1751
