There are 92 girls and boys altogether.
45 of the number of girls is 16 more than the number of boys.
- How many girls are there?
- How many more girls than boys are there?
(a)
Number of girls = 5 u
Number of boys = 4 u - 16
Number of children
= 5 u + 4 u - 16
= 9 u - 16
9 u - 16 = 92
9 u = 92 + 16
9 u = 108
1 u = 108 ÷ 9 = 12
Number of girls
= 5 u
= 5 x 12
= 60
(b)
Number of boys
= 92 - 60
= 32
Number of more girls than boys
= 60 - 32
= 28
Answer(s): (a) 60; (b) 28
