There are 204 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 = 204
11 u = 204 + 16
11 u = 220
1 u = 220 ÷ 11 = 20
Number of boys
= 6 u
= 6 x 20
= 120
(b)
Number of girls
= 204 - 120
= 84
Number of more boys than girls
= 120 - 84
= 36
Answer(s): (a) 120; (b) 36
