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.

How old is Ishaan now?

Answer 1

Ishaan's Age now is 7 years

Using the system of equation:

• Ben, x
• Ishaan, y =

x = y + 12 ___(1)

x - 3 = 4y - 12 ___(2)

From (1)

Input (1) into (2)

y + 12 - 3 = 4y - 12

y + 9 = 4y - 12

y - 4y = -12 -9

-3y = -21

y = 7

Hence, Ishaan's Age now is 7 years
