(a)
Number of children
= 4 u + 7 u
= 11 u
11 u = 66
1 u = 66 ÷ 11 = 6
Total number of stickers
= 32 u + 28 u
= 60 u
= 60 x 6
= 360
(b)
Number of less girls than boys
= 7 u - 4 u
= 3 u
= 3 x 6
= 18
(c)
Number of less stickers are given to the boys than the girls
= 32 u - 28 u
= 4 u
= 4 x 6
= 24
Answer(s): (a) 360; (b) 18; (c) 24
