Let the present age of A be x and B be y.
As per statement, A is 20 years older than B.Thus
x = 20 + y --------Eq 1
5 years ago, A was 3 times old as B. Accordingly, 5 years ago their ages, A's age x - 5 and B's age y - 5
(x - 5) = 3 (y - 5)
x - 5 = 3y - 15
x - 3y = 5 - 15
x - 3y = -10…Eq..2
Substituting value if x from Eq..1 to Eq..2
x - 3y = -10
20 + y - 3y = -10
y - 3y = -20 -10
-2y = -30
2y = 30
y = 30/2
y = 15
Substituting the value of y in Eq..1 to derive value of x
x = 20 + y
x = 20 + 15
x = 35
The present age of A is 35 years and present age of B is 15 years
