There are 82 girls and boys altogether.
34 of the number of girls is 16 more than the number of boys.
- How many girls are there?
- How many more girls than boys are there?
(a)
Number of girls = 4 u
Number of boys = 3 u - 16
Number of children
= 4 u + 3 u - 16
= 7 u - 16
7 u - 16 = 82
7 u = 82 + 16
7 u = 98
1 u = 98 ÷ 7 = 14
Number of girls
= 4 u
= 4 x 14
= 56
(b)
Number of boys
= 82 - 56
= 26
Number of more girls than boys
= 56 - 26
= 30
Answer(s): (a) 56; (b) 30
