Answer 1

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.
