Question 1051471
 If rose was four time younger than alice last year.
And will be half the age of George in two years time.
How old is now alice? If George will be 21 next year.
----
Let Alice be "A" yrs old now.
Let Rose be "R" yrs old now.
---------
Equations:
R-1 = (A-1)/4
R+2 = (1/2)(G+2)
G+1 = 21
----------------------
G = 20
Solve for "R"::
So, R+2 = (1/2)(22) = 11 yrs 
R = 9 yrs (Rose's age now)
-----------------------
Solve for A::
9-1 = (A-1)/4
A-1 = 8*4
A = 33 yrs (Alice's age now)
