Gem gave 12% of her collection of beads to Kylie thereby increasing Kylie's collection by 20%. If Gem had 44 beads left, how many beads did Kylie have at first?
| |
Gem's beads |
Kylie's beads |
| Before |
100% |
100 u |
| Change |
- 12% |
+ 12% = + 20 u |
| After |
88% |
120 u |
88% of Gem's collection = 44
1% of Gem's collection = 44 ÷ 88 = 0.5
12% of Gem's collection = 12 x 0.5 = 6
20 u of Kylie's collection = 6
1 u of Kylie's collection =
630 = 0.3
100 u of Kylie's collection = 100 x 0.3 = 30
Answer(s): 30
