What is the percentage of vacant seats across all four colleges together?

A17.66

B15.66

C14.22

D16.67 ✓ Correct

Correct answer: (D) 16.67

Explanation

The answer is about 16.67 percent.

The total number of seats is 3000.

The total admitted is 2500, so 500 seats stay vacant.

So the vacant share is 500 divided by 3000, times 100.

That is about 16.67 percent.

The other options do not match this value.

So the answer is about 16.67 percent.
