(a)
Number of children
= 5 u + 7 u
= 12 u
12 u = 96
1 u = 96 ÷ 12 = 8
Total number of stickers
= 40 u + 14 u
= 54 u
= 54 x 8
= 432
(b)
Number of less girls than boys
= 7 u - 5 u
= 2 u
= 2 x 8
= 16
(c)
Number of less stickers are given to the boys than the girls
= 40 u - 14 u
= 26 u
= 26 x 8
= 208
Answer(s): (a) 432; (b) 16; (c) 208
