The answer sheet shows 44 instead of 88.
I don’t understand why number of boys is 1u + 4. How to get 1u + 4?

2 groups have same number of members.
If 1st group is 2u + 20... the other group also same. Since the girls have 12 more... so 16-4 =12.

Answer 44 is correct.
Boy 11u
Girl 9u
2u = 8
1u = 4 not 8
Boy= 11u= 11 x 4 = 44.
