There are 92 boys and girls altogether.
27 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 = 7 u
Number of girls = 2 u - 16
Number of children
= 7 u + 2 u - 16
= 9 u - 16
9 u - 16 = 92
9 u = 92 + 16
9 u = 108
1 u = 108 ÷ 9 = 12
Number of boys
= 7 u
= 7 x 12
= 84
(b)
Number of girls
= 92 - 84
= 8
Number of more boys than girls
= 84 - 8
= 76
Answer(s): (a) 84; (b) 76
