Solution

This statement is True.

Explanation:

Let the age of A be x years.

Then, age of B = (90 – x) years

Five years ago, the age of A = (x – 5) years

The age of B = 90 – x – 5 = (85 – x) years

Hence, the ages of A and B five years back would be (x – 5) years and (85 – x) years, respectively.
