Question

Ben is 12 years older than Ishaan. Ben and Ishaan first met two years ago. Three years ago, Ben was 4 times as old as Ishaan?

Answer 1

The first statement means:

b=i+12,

The third statement means:

b-3=4(i-3),

b-3=4i-12

b=4i-9

Using the value for b from the first statement in the third statement gives you:

i+12=4i-9

-3i=-21

i=7: and since b=i+12

b=19

So Ben is 19 and Ishaan is 7.
