Answer:
66% have graduated within five years.
Step-by-step explanation:
It is given that 70% of freshmen went to public schools. Then the rest 30% i.e., should have gone to other schools.
Now, the number the freshmen in public schools is considered as 100% or 1.
60% of the freshmen from public schools have graduated means out of the total freshmen from public schools, 60% of them have graduated. That is why it is denoted as 0.6 and those not graduated as 0.4.
Note that 60% of total students have graduated.
Let us assume there were 100 students initially. Then 70 students went to public school. Number of students graduated = 60%
That is 42 students have passed from public school.
Now, the ones in other schools:
80% of them have graduated in other schools. That means out of total students 80% of them have graduated.
That means
24 students from other schools have passed.
Therefore, totally 66 students have passed. i.e., 66 percent have passed.
