There are 110 girls and boys altogether.
56 of the number of girls is 11 more than the number of boys.
- How many girls are there?
- How many more girls than boys are there?
(a)
Number of girls = 6 u
Number of boys = 5 u - 11
Number of children
= 6 u + 5 u - 11
= 11 u - 11
11 u - 11 = 110
11 u = 110 + 11
11 u = 121
1 u = 121 ÷ 11 = 11
Number of girls
= 6 u
= 6 x 11
= 66
(b)
Number of boys
= 110 - 66
= 44
Number of more girls than boys
= 66 - 44
= 22
Answer(s): (a) 66; (b) 22
