Ben is 121212 years older than ishaan. ben and ishaan first met two years ago. three years ago, ben was 444 times as old as ishaan.

Let Ishaan be x years old.

Ishaan = x
Ben = x + 12

3 years ago,
Ishaan = x - 3 
Ben = x + 12 - 3 = x + 9

Ben was 4 times as old as Ishaan.
x + 9 = 4(x - 3)
x + 9 = 4x - 12
4x - x= 12 + 9 
3x = 21
x = 7

Find their ages:
Ishaan = x = 7
Ben = x + 12 = 7 + 12 = 19

Ishaan is 7 years old and Ben is 19 years old.
