| Change |
- 1.32 u |
- 0.32 u |
| After |
0.68 u |
0.68 u |
Number of women that left
= 32% x 1 u
=
32100 x 1 u
= 0.32 u
Number of women that remained
= 1 u - 0.32 u
= 0.68 u
Number of men that needed to leave = 2 u - 0.68 u= 1.32 u Percentage of men that must leave = 1.322 x 100% = 66% Answer(s): 66%
