Ben is 4 times old as ishaan. 6 years ago, Ben was 6 times as old as ishaan

How old is Ben now?

60years

Step-by-step explanation:

let Ben age = x

ishaan age = y

Ben is 4 times old as ishaan:

x=4y ... equation (1)

6 years ago

Ben age = x-6

Ishaan age = y-6

x-6=6 (y-6)

x-6=6y-36

x=6y-36+6

x=6y-30 ... equation (2)

equating equation (1) and (2)

4y=6y-30

4y-6y=-30

-2y=-30

y=-30/-2=15

substituting the value of y into equation (1)

x=4y

=4*15

=60

Ben age now = 60years
