There are 194 boys and girls altogether.
56 of the number of boys is 4 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 - 4
Number of children
= 6 u + 5 u - 4
= 11 u - 4
11 u - 4 = 194
11 u = 194 + 4
11 u = 198
1 u = 198 ÷ 11 = 18
Number of boys
= 6 u
= 6 x 18
= 108
(b)
Number of girls
= 194 - 108
= 86
Number of more boys than girls
= 108 - 86
= 22
Answer(s): (a) 108; (b) 22
