(a)
Number of children
= 5 u + 8 u
= 13 u
13 u = 104
1 u = 104 ÷ 13 = 8
Total number of stickers
= 40 u + 24 u
= 64 u
= 64 x 8
= 512
(b)
Number of less boys than girls
= 8 u - 5 u
= 3 u
= 3 x 8
= 24
(c)
Number of less stickers are given to the girls than the boys
= 40 u - 24 u
= 16 u
= 16 x 8
= 128
Answer(s): (a) 512; (b) 24; (c) 128
