Sarah had 120 white beads and 60 grey beads. Sarah gave away 30% of her white beads and 65% of her grey beads. What percentage of her beads left was grey?
Percentage of white beads left
= 100% - 30%
= 70%
Number of white beads left
= 70% x 120
= 70100 x 120
= 84
Percentage of grey beads left
= 100% - 65%
= 35%
Number of grey beads left
= 35% x 60
=
35100 x 60
= 21
Total number of beads left
= 84 + 21
= 105
Percentage of beads left that are grey
=
21105 x 100%
= 20%
Answer(s): 20%
