(a)
Number of beads that Lucy won from Cindy
=
14 x 72
= 18
Number of beads that Lucy lost to Roshel
=
58 x 72
= 45
Number of beads that Lucy won from Cindy
=
12 x 72
= 36
Number of beads that Lucy had in the end
= 72 + 18 - 45 + 36
= 81
(b)
Number of beads that Cindy had at first
= 1 u + 36 + 45 + 18
= 81 + 36 + 45 + 18
= 180
Answer(s): (a) 81 ; (b) 180
