Answer:
Age of X = 40 years
Age of Y = 15 years
Step-by-step explanation:
Let present ages of X be x years
Y be y years.
Case 1
10 Years hence or 10 years after
Age of X = (x+10) years
Age of Y = (y+10) years
A.T.Q
(x+10) = 2(y+10)
x-2y = 10 - eq.1
Case 2
10 Years ago or before
Age of X = (x-10) years
Age of Y = (y-10) years
A.T.Q
(x-10) = 6(y-10)
x-6y = -50 - eq.2
