Number of beads that Glen had at first in percent
= 100% + 40%
= 140%
Number of beads that Glen gave to Andy in percent
= 10% x 140%
=
10100 x 140%
= 14%
Number of beads that Andy gave to Glen in percent
= 50% x 114%
=
50100 x 114%
= 57%
Number of less beads that Andy had than Glen in the end
= 183% - 57%
= 126%
126% → 1260
1% → 1260 ÷ 126 = 10
Number of beads that Andy had in the end
= 57%
= 57 x 10
= 1400
