Question

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. How old is Ishaan now?

Answer 1

Let's say Ben = X and  Ishaan= Y.

Ben is 12 years older than Ishaan is equal to

$X=12+Y$

Three years ago, Ben was 4 times as old as Ishaan.

$X-3=4*Y$

Now, you have two incognitas and two equations, you can solve it.

$(12+Y)-3=4*Y\\12-3=4Y-Y\\9=3Y\\\frac{9}{3}=Y \\3=Y$

And now you can use this number to know Ben's age.

$X=12+Y$\\$X=12+3$\\$X=15$

• Ben's age: 15
• Ishaan's age: 3

Answer 2

Ishaan is 53816799 (121212-3(444)+3)
