(a)
Number of beads that Abi won from Jean
=
45 x 40
= 32
Number of beads that Abi lost to Barbara
=
58 x 40
= 25
Number of beads that Abi won from Jean
=
14 x 40
= 10
Number of beads that Abi had in the end
= 40 + 32 - 25 + 10
= 57
(b)
Number of beads that Jean had at first
= 1 u + 10 + 25 + 32
= 57 + 10 + 25 + 32
= 124
Answer(s): (a) 57 ; (b) 124
