a. 13 years
b. 27950 students

Let x be the number of years since the initial year 2005. In 2005, , in 2006, , and so on.
For college "A" the number of students is given by the function:
For college "B" the number of students is given by the function:
Matching these expressions you have the value of x for which the two colleges have the same number of students.
Then, the two colleges will have the same number of students 13 years later, that is, in 2018.
The number of students that each colleges will have in 2018 will be students.
He has 20 pencils.
The ratio in the problem is 4 pens to 5 pencils meaning for every 4 pens there are 5 pencils.
So take this into mathematics 16pens/4pens = 4
5pencils * 4 is equal to 20 pencils
the ratio still works and it is still 4 to 5 so the answer is 20...pencils.
