If the enrollment at State U. was 3,000 in 1965 and 12,000 in 1990, what was the percent of increase in enrollment?

(A) 3%
(B) 25%
(C) 125%
(D) 300%
(E) 400%


The enrollment saw an increase of \(9000(12000-3000)\) from 3000 in 1965 to 12000 in 1990.

Therefore, the percentage increase in enrollment is \(\frac{9000}{3000}*100 = 300\)% (Option D)

IMO D
12000-3000*100/3000
9000*100/3000= 3*100

% increase= \(\frac{Change}{Initial Value}\)*100

= \(\frac{(12000-3000)}{3000}\)*100

= \(\frac{9000}{3000}\)*100

= 300%

Answer: D.

In general, if the final value is K times the initial value, then the increase is always (K-1)*100 %.

In this particular case K=4.
