There are 114 boys and girls altogether.
34 of the number of boys is 5 more than the number of girls.
- How many boys are there?
- How many more boys than girls are there?
(a)
Number of boys = 4 u
Number of girls = 3 u - 5
Number of children
= 4 u + 3 u - 5
= 7 u - 5
7 u - 5 = 114
7 u = 114 + 5
7 u = 119
1 u = 119 ÷ 7 = 17
Number of boys
= 4 u
= 4 x 17
= 68
(b)
Number of girls
= 114 - 68
= 46
Number of more boys than girls
= 68 - 46
= 22
Answer(s): (a) 68; (b) 22
