(a)
Number of children
= 5 u + 7 u
= 12 u
12 u = 84
1 u = 84 ÷ 12 = 7
Total number of stickers
= 40 u + 14 u
= 54 u
= 54 x 7
= 378
(b)
Number of less boys than girls
= 7 u - 5 u
= 2 u
= 2 x 7
= 14
(c)
Number of less stickers are given to the girls than the boys
= 40 u - 14 u
= 26 u
= 26 x 7
= 182
Answer(s): (a) 378; (b) 14; (c) 182
