Ben is 19 and Ishaan is 7.
If 3 years ago Ben was 4 times the age of Ishann, their ages could have been any of the following:
1. Ben is 4 and Ishaan is 1
2. Ben is 8 and Ishaan is 2
3. Ben is 12 and Ishaan is 3
4. Ben is 16 and Ishaan is 4
And so on.
Next add 3 to both ages, to show current age.
1. Ben is 7 and Ishaan is 4
2. Ben is 11 and Ishaan is 5
3. Ben is 15 and Ishaan is 6
4. Ben is 19 and Ishaan is 7
Ben is currently 12 years older than Ishaan. To find the difference, take Ben's age and subtract Ishaan's age.
1. 7 - 4 = 3
2. 11 - 5 = 6
3. 15 - 6 = 9
4. 19 - 7 = 12
Thus meaning Ben is 19 and Ishaan is 7.
I hope this helps!
