Answer 2

$<b>Answer:</b>$

15 years

$<b>Step-by-step explanation:</b>$

Let the son's present age is 'x'.

Then the father's present age is 3x.

$<b>Five years later:</b>$

Age of son = x + 5.

Age of father = 3x + 5.

$<b>According to the given condition,</b>$

⇒ 3x + 5 = (5/2)[x + 5]

⇒ 6x + 10 = 5[x + 5]

⇒ 6x + 10 = 5x + 25

⇒ x = 15

When x = 15:

Then, 3x = 45.

Therefore:

$<b>Present age of Summit = 15 years.</b>$
