Answer 2

Answer:

The mathematics teacher is 48 years old.

Step-by-step explanation:

Given - the teacher's son is 24 years younger
            the teacher's grandson is 23 years younger than his son, i.e., 47 years younger than him
            the sum of their ages is 73 years

To find - the teacher's age

Solution -

Let us consider the teacher's age to be $x$

Then, the teacher's son's age would be $x-24$

Because the grandson is 25 years younger than his son, his age would be $(x-24)-25$

We are also given that the sum of their ages is 73 years.

Thus, we can be written this as and the simplified to be $x + (x-24) + (x-24)-25 = 73\\3x - 73 = 73\\3x = 146\\x = 48$

Thus, the teacher is 48 years old.
