Answer:
No, this situation is not possible.
Step-by-step explanation:
present age x, 20-x
four years ago,
(x-4) ×(20-x-4)=48
(x-4) ×(16-x)=48
16x-64-x^2+4x=48
x^2-20x+112=0
if we calculate determinant of this quadratic then we get <0 this implies no such real situation is possible.
D=(-20)^2-4×1×112<0.
