There are 610 people,
of which 60 are women.
There are 540 less adults than men.
- How many children are there?
- How many adults are there?
- How many less children than adults are there?
- How many more men than women are there?
(a)
Number of women = 60
Number of children = 1 u
Number of men = 1 u + 540
Total number of people
= 60 + 1 u + 1 u + 540
= 1 u + 1 u + 60 + 540
= 2 u + 600
2 u + 600 = 610
2 u = 610 - 600
2 u = 10
1 u = 10 ÷ 2 = 5
Number of children
= 1 u
= 5
(b)
Number of adults
= 60 + 1 u + 540
= 60 + 5 + 540
= 605
(c)
Number of less children than adults
= 605 - 5
= 600
(d)
Number of more men than women
= 1 u + 540 - 60
= 5 + 540 - 60
= 485
Answer(s): (a) 5; (b) 605; (c) 600; (d) 485
