There are 94 girls and boys altogether.
27 of the number of girls is 14 more than the number of boys.
- How many girls are there?
- How many more girls than boys are there?
(a)
Number of girls = 7 u
Number of boys = 2 u - 14
Number of children
= 7 u + 2 u - 14
= 9 u - 14
9 u - 14 = 94
9 u = 94 + 14
9 u = 108
1 u = 108 ÷ 9 = 12
Number of girls
= 7 u
= 7 x 12
= 84
(b)
Number of boys
= 94 - 84
= 10
Number of more girls than boys
= 84 - 10
= 74
Answer(s): (a) 84; (b) 74
