(a)
Number of beads that Marion won from Lynn
=
34 x 28
= 21
Number of beads that Marion lost to Hilda
=
37 x 28
= 12
Number of beads that Marion won from Lynn
=
12 x 28
= 14
Number of beads that Marion had in the end
= 28 + 21 - 12 + 14
= 51
(b)
Number of beads that Lynn had at first
= 1 u + 14 + 12 + 21
= 51 + 14 + 12 + 21
= 98
Answer(s): (a) 51 ; (b) 98
