There are 58 boys and girls altogether.
34 of the number of boys is 19 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 - 19
Number of children
= 4 u + 3 u - 19
= 7 u - 19
7 u - 19 = 58
7 u = 58 + 19
7 u = 77
1 u = 77 ÷ 7 = 11
Number of boys
= 4 u
= 4 x 11
= 44
(b)
Number of girls
= 58 - 44
= 14
Number of more boys than girls
= 44 - 14
= 30
Answer(s): (a) 44; (b) 30
