(a)
Number of beads that Anna won from Hilda
=
14 x 32
= 8
Number of beads that Anna lost to Fiona
=
58 x 32
= 20
Number of beads that Anna won from Hilda
=
12 x 32
= 16
Number of beads that Anna had in the end
= 32 + 8 - 20 + 16
= 36
(b)
Number of beads that Hilda had at first
= 1 u + 16 + 20 + 8
= 36 + 16 + 20 + 8
= 80
Answer(s): (a) 36 ; (b) 80
