(a)
Number of beads that Fanny won from Tiffany
=
25 x 40
= 16
Number of beads that Fanny lost to Diana
=
38 x 40
= 15
Number of beads that Fanny won from Tiffany
=
15 x 40
= 8
Number of beads that Fanny had in the end
= 40 + 16 - 15 + 8
= 49
(b)
Number of beads that Tiffany had at first
= 1 u + 8 + 15 + 16
= 49 + 8 + 15 + 16
= 88
Answer(s): (a) 49 ; (b) 88
