(a)
Number of children = 1 u
Number of adults = 5 x 1 u = 5 u
Total number of people
= 5 u + 1 u
= 6 u
6 u = 636
1 u = 636 ÷ 6 = 106
(a)
Number of adults
= 5 u
= 5 x 106
= 530
(b)
Number of men = 1 p
Number of women = 1 p + 64
1 p + 1 p + 64 = 530
2 p + 64 = 530
2 p = 530 - 64
2 p = 466
1 p = 466 ÷ 2 = 233
Number of men
= 1 p
= 233
(c)
Number of women
= 1 p + 64
= 233 + 64
= 297
Answer(s): (a) 530; (b) 233; (c) 297
