1. What was the ratio of the number of children to men to women visiting the tourist attraction on Sunday?
2. On Saturday, 704 men and women visited the tourist attraction. What was the total number of visitors at the tourist attraction on Sunday?

	Children	Men	Women
Before	5 u	10 u	6 u
Change		+ 5 u	- 3 u
After	5 u	15 u	3 u

(a)
Increase in the number of men
= 50% x 10 u
= ⁵⁰₁₀₀ x 10 u
= 5 u

Decrease in the number of women
= 50% x 6 u
= ⁵⁰₁₀₀ x 6 u
= 3 u

Number of men on Sunday
= 10 u + 5 u
= 15 u

Number of women on Sunday
= 6 u - 3 u
= 3 u

On Sunday
Children : Men : Women
5 : 15 : 3

(b)
Number of men and women on Saturday
= 10 u + 6 u
= 16 u

16 u = 704

1 u = 704 ÷ 16 = 44

Total number of visitors on Sunday
= 5 u + 15 u + 3 u
= 23 u
= 23 x 44
= 1012

Answer(s): (a) 5 : 15 : 3; (b) 1012
