(a)
Number of children
= 5 u + 8 u
= 13 u
13 u = 104
1 u = 104 ÷ 13 = 8
Total number of stickers
= 35 u + 32 u
= 67 u
= 67 x 8
= 536
(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
= 35 u - 32 u
= 3 u
= 3 x 8
= 24
Answer(s): (a) 536; (b) 24; (c) 24
