There are 114 boys and girls altogether.
37 of the number of boys is 6 more than the number of girls.
- How many boys are there?
- How many more boys than girls are there?
(a)
Number of boys = 7 u
Number of girls = 3 u - 6
Number of children
= 7 u + 3 u - 6
= 10 u - 6
10 u - 6 = 114
10 u = 114 + 6
10 u = 120
1 u = 120 ÷ 10 = 12
Number of boys
= 7 u
= 7 x 12
= 84
(b)
Number of girls
= 114 - 84
= 30
Number of more boys than girls
= 84 - 30
= 54
Answer(s): (a) 84; (b) 54
