There are 500 people,
of which 110 are women.
There are 140 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 = 110
Number of children = 1 u
Number of men = 1 u + 140
Total number of people
= 110 + 1 u + 1 u + 140
= 1 u + 1 u + 110 + 140
= 2 u + 250
2 u + 250 = 500
2 u = 500 - 250
2 u = 250
1 u = 250 ÷ 2 = 125
Number of children
= 1 u
= 125
(b)
Number of adults
= 110 + 1 u + 140
= 110 + 125 + 140
= 375
(c)
Number of less children than adults
= 375 - 125
= 250
(d)
Number of more men than women
= 1 u + 140 - 110
= 125 + 140 - 110
= 155
Answer(s): (a) 125; (b) 375; (c) 250; (d) 155
