There are 120 professors at the university
Step-by-step explanation:
At one really small university:
- There are 1,200 people
- 53% are undergraduates
- 37% are graduates
- The rest are going for their doctorate
We need to find how many professors are at the university
Assume that the number of people the university is 100%
∵ 53% of the people in the university are undergraduates
∵ 37% of the people in the university are graduates
∵ There are 100% people in the university
- To find the rest subtract the sum of the undergraduates and
graduates from 100%
∵ The rest = 100% - (53% + 37%)
∴ The rest = 100% - 90%
∴ The rest = 10%
∴ The rest is 10% from 1200 people in the university
∵ The rest are going for their doctorate
∴ The rest is the number of the professors in the university
∵ The rest is 10% from 1200 people in the university
∴ The number of professors = 10% × 1200
∵ 10% = 10 ÷ 100 = 0.1
∴ The number of professors = 0.1 × 1200
∴ The number of professors = 120
There are 120 professors at the university
