(a)
Total number of beads at first
= 8 u + 2 u + 26 + 1 u
= 11 u + 26
11 u + 26 = 147
11 u = 147 - 26
11 u = 121
1 u = 121 ÷ 11 = 11
Number of less beads in Basket J than Basket H at first
= 8 u - (2 u + 26)
= 8 u - 2 u - 26
= 6 u - 26
= 6 x 11 - 26
= 66 - 26
= 40
(b)
Total number of beads in Basket J and Basket K in the end
= 2 u + 3 u
= 5 u
= 5 x 11
= 55
Answer(s): (a) 40; (b) 55
