(a)
Number of children
= 4 u + 7 u
= 11 u
11 u = 132
1 u = 132 ÷ 11 = 12
Total number of stickers
= 24 u + 14 u
= 38 u
= 38 x 12
= 456
(b)
Number of less girls than boys
= 7 u - 4 u
= 3 u
= 3 x 12
= 36
(c)
Number of less stickers are given to the boys than the girls
= 24 u - 14 u
= 10 u
= 10 x 12
= 120
Answer(s): (a) 456; (b) 36; (c) 120
