(a)
If another 124 silver beads are added into the box at first, the number of grey and silver beads will be the same.
10 u = 4 u + 56 + 124
10 u - 4 u = 56 + 124
6 u = 180
1 u = 180 ÷ 6 = 30
Number of beads that Asher took out
= 10 u + 4 u
= 14 u
= 14 x 30
= 420
(b)
Number of beads that Asher had at first
= 420 + 56
= 476
Answer(s): (a) 420; (b) 476
