There are 157 boys and girls altogether.
45 of the number of boys is 14 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 = 4 u - 14
Number of children
= 5 u + 4 u - 14
= 9 u - 14
9 u - 14 = 157
9 u = 157 + 14
9 u = 171
1 u = 171 ÷ 9 = 19
Number of boys
= 5 u
= 5 x 19
= 95
(b)
Number of girls
= 157 - 95
= 62
Number of more boys than girls
= 95 - 62
= 33
Answer(s): (a) 95; (b) 33
