Question

Jeremy is 15 years old. His father is 4 times as old as him now.
In how many years time will their total age be 115 years

Answer 1

Step-by-step explanation:

If the son is 15, then the father, who is 4 times as old, must be 60 years old. Then the current sum of their ages is 15 + 60 = 75.

You must add 40 to 75 to get to 115. Since 2 is added to the sum of their ages every year, it will take 20 years to increase the sum of their ages by 40.

Answer 2

In how many years time will their total age be 115 years? If the son is 15, then the father, who is 4 times as old, must be 60 years old

Then the current sum of their ages is 15 +60 = 75

I hope it's help you
