Question 259513
Lets say Jay is "X" yrs old today.  --> Statement (1)

Lets say Jay was "Y" yrs old when Mike was what Jay is today that is "X" yrs old.  --> Statement (2)

So in short,
Lets say Jay was "Y" yrs old when Mike was "X" yrs old.   --> Statement (3)

Now we know from the problem that Mike is 33 yrs old now which is 3 times when Jay was "Y" yrs old.

So,

3Y = 33
Y = 11.

So when Jay was 11 yrs old Mike was "X" yrs old.  (From Statement (3) )

Now Mike is 33 today. Lets say it took Mike "Z" yrs to reach 33 from when he was "X"
So,
X + Z = 33
Z = 33 - X  --> (4)


Now Jay is "X" yrs old today --> (From Statement (1) )
It took him the same "Z" yrs to reach "X" from when he was 11.
So,

11 + Z = X
Z = X - 11  --> (5)

From (4) and (5)
33 - X = X - 11
33 + 11 = X + X
44 = 2X
44/2 = X
X = 22

So Jay 22 yrs old today.

Verification:
---------------

Mike is 33 today which is 3 times what Jay was which is 11 when Mike was the age what Jay is today which is 22.
