Question

4 years before paul's age is 3times the alice age and the present age of paul is 6times the alice. what is the presents paul's age

Answer 1

Let the present age of Alice is x and Paul is y.
4 years ago paul age=y-4

Then,
3x=y-4
x=y-4/3 ....(1)

y=6x
y= 6 (y-4/3)
y=2 (y-4)
y=2y-8
y-2y= -8
-y= -8
y=8

Hence,Paul's present age is 8 years.
