Question

When Tom was born, his father was 30 years old. Now Tom is 30 years old. What is the average age of Tom and Tom's father now? Why?

Answer 1

45 years old

Explanation:

If Tom's father was 30 when Tom was born, he must be 30 years older than Tom. Therefore, if Tom is now 30, his father must be 60 years old (30+30)

Now, to find the average age of the two, we can add 30 and 60 together and divide by two.

= (30 + 60)/ 2

= 90/2

= 45 years old
