Answer:
350 candidates
Step-by-step explanation:
It is given that:
- 450 candidates apply for admission
- 10 candidates are over age, so they do not take the exam
- 20% of them fail the exam
It is required to know how many will qualify for admission.
First of all, we need to calculate how many the 20% that fail the exam are.
Therefore, 20% of the 450 candidates = 0.2*450 = 90 candidates.
Hence, the number of people that qualify = 450 - (90+10) = 450 - 100
= 350 candidates
