There are 138 boys and girls altogether.
56 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 = 6 u
Number of girls = 5 u - 16
Number of children
= 6 u + 5 u - 16
= 11 u - 16
11 u - 16 = 138
11 u = 138 + 16
11 u = 154
1 u = 154 ÷ 11 = 14
Number of boys
= 6 u
= 6 x 14
= 84
(b)
Number of girls
= 138 - 84
= 54
Number of more boys than girls
= 84 - 54
= 30
Answer(s): (a) 84; (b) 30
