Cheryl Diana
at first 2u u

Cheryl used 6 beads a day while Diana used 8 beads a day.
Assume that they take x days

used 6x 8x

Left 70 0

Cheryl has 6x+70 beads
Diana has 8x+0 beads
Given that Cheryl has 2 times number of beads than Diana,

==> 6x+70 = 2(8x)
6x+70 = 16x
10x = 70
x = 7

Diana took 7 days to use up her beads.
