Question

A teacher is four times as old as a student. In 24 years, the student's age will be half of the teacher's age. How old are they now?

The age of the teacher is
years.

Answer 1

Student is 12 now, teacher is 48

Explanation:

Let s be students current age

Let t be teachers current age

Currently:

4s = t

In 24 Years:

2(s+24)=t+24

2s+48=4s+24

2s=24

s=12 The student is 12 now

t=48 The teacher is 48 now
