Answer 2

Step-by-step explanation:

Let the man's age be ab and the son's age be ba.

Now we are given that the sum of their ages is 77.

So ab + ba = 77

=> 10a + b + 10b + a = 77

=> 11a + 11b = 77

=> a + b = 7

If a = 7 , b = 0

If a = 6, b = 1

If a = 5, b = 2

For values of a = 3 , 2 , 1 and 0 the son's age is no longer less than the man.

(70, 7), (61 ,16) and (52 , 25)
