(a)
Number of beads that Jade won from Min
=
34 x 32
= 24
Number of beads that Jade lost to Kylie
=
18 x 32
= 4
Number of beads that Jade won from Min
=
12 x 32
= 16
Number of beads that Jade had in the end
= 32 + 24 - 4 + 16
= 68
(b)
Number of beads that Min had at first
= 1 u + 16 + 4 + 24
= 68 + 16 + 4 + 24
= 112
Answer(s): (a) 68 ; (b) 112
