Here are the equations:
(1) Jean = Jane - 12
(2) Joan = Jean * 2
(3) Joan - 4 = Jane
(4) Jane - 4 = Jean * 2
Solve the two Jean/Jane equations:
(4) becomes: Jane = (Jean * 2) +4
and then (1) becomes
Jean = ((Jean * 2) +4) - 12
or
Jean = 8
Checking the math:
(1) Jean = Jane - 12
so Jane = 20
(2) Joan = Jean * 2
so Joan = 16
(3) Joan - 4 = Jane
(correct)
(4) Jane - 4 = Jean * 2
(correct)

Jean is 16 years old now.
so joan is 32 now and jane is 28. 4 years ago joan was 28 (as jane now) and jane was 24 (twice of then jean's age).

Thats impossible to answer. It all depends on what age Joan had her daughter...and that can vary.
