In your example, no quotas would result in all 14 hires being those with a qualification of 100. Congrats, got all 5 minorities without quotas!

Now for some thing more realistic: Instead of making those 14 candidates all perfect, distribute them a bit more randomly and only hire the top 10. Without quotas you'll end up with around 4 from the minority group and 6 from the majority group. But if for example your quotas are for 50/50, you have to exclude 1 person from the majority group who is more qualified than the 5th person from the minority group to reach it.
