Bill is three times as old as Mary. Bill is 48. How old will Bill be when he is twice as old as Mary?
----------
Equations::
b = 3m
b = 48
----
So 3m = 48
And M = 16 (Mary's age now)
Therefore Bill = 3m = 3*16 = 48 (Bill's age now)
------
Equation::
48+x = 2(16+x)
48+x = 32 + 2x
x = 16 yrs
----
Bill will be twice Mary's age when Bill is 48+16 = 64
Mary will then be 16+x = 16+16 = 32
