There are 72 boys and girls altogether.
35 of the number of boys is 16 more than the number of girls.
- How many boys are there?
- How many more boys than girls are there?
(a)
Number of boys = 5 u
Number of girls = 3 u - 16
Number of children
= 5 u + 3 u - 16
= 8 u - 16
8 u - 16 = 72
8 u = 72 + 16
8 u = 88
1 u = 88 ÷ 8 = 11
Number of boys
= 5 u
= 5 x 11
= 55
(b)
Number of girls
= 72 - 55
= 17
Number of more boys than girls
= 55 - 17
= 38
Answer(s): (a) 55; (b) 38
