Answer:
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
