b 273
c 234

Explanation:

Step1: Find total number of students

Let the total number of students be $x$. Since freshmen are 28% of the total and there are 420 freshmen, we have the equation $0.28x = 420$. Solving for $x$, we get $x=\frac{420}{0.28}=1500$.

Step2: Find number of seniors

Seniors are 24% of the total number of students. So the number of seniors is $0.24\times1500 = 360$.

Step3: Find number of seniors going to college

65% of the seniors will attend college next - year. So the number of seniors going to college is $0.65\times360=234$.
