(a)
Number of children
= 5 u + 8 u
= 13 u
13 u = 143
1 u = 143 ÷ 13 = 11
Total number of stickers
= 30 u + 24 u
= 54 u
= 54 x 11
= 594
(b)
Number of less girls than boys
= 8 u - 5 u
= 3 u
= 3 x 11
= 33
(c)
Number of less stickers are given to the boys than the girls
= 30 u - 24 u
= 6 u
= 6 x 11
= 66
Answer(s): (a) 594; (b) 33; (c) 66
