(a)
Number of children
= 3 u + 8 u
= 11 u
11 u = 121
1 u = 121 ÷ 11 = 11
Total number of stickers
= 18 u + 16 u
= 34 u
= 34 x 11
= 374
(b)
Number of less girls than boys
= 8 u - 3 u
= 5 u
= 5 x 11
= 55
(c)
Number of less stickers are given to the boys than the girls
= 18 u - 16 u
= 2 u
= 2 x 11
= 22
Answer(s): (a) 374; (b) 55; (c) 22
