(a)
Number of children
= 5 u + 8 u
= 13 u
13 u = 130
1 u = 130 ÷ 13 = 10
Total number of stickers
= 35 u + 24 u
= 59 u
= 59 x 10
= 590
(b)
Number of less boys than girls
= 8 u - 5 u
= 3 u
= 3 x 10
= 30
(c)
Number of less stickers are given to the girls than the boys
= 35 u - 24 u
= 11 u
= 11 x 10
= 110
Answer(s): (a) 590; (b) 30; (c) 110
