Sandy: 1 unit
Mandy: 2 units (twice as many as Sandy)
Gerry: 6 units (3 times as many as Mandy)
Difference between Gerry and Sandy: 5 units
Total number of beads: 9 units
5 units = 7 465 beads
1 unit = 7 465 / 5 = 1 493 beads
9 units = 1 493 x 9 = 13 437 besds
So they have 13 437 beads altogether.

Thank you. I made a mistake in Sandy computation. If not, will be able to get the same amt.
