Given Munnu’s age to be x years, can you gues what (x – 2) may show?

Can you gues what x + 4 may show? What (3x+7) may show?

Here,

According to the question,

We can conclude that,

(x – 2) represents that the person, whose age is (x – 2) years, is two years younger to Munnu.

And,

(x + 4) represents that the person, whose age is (x + 4) years, is four years elder to Munnu.

And,

(3x + 7) represents that the person, whose age is (3x + 7) years, is elder to Munnu and his age is 7 years more than thrice the age of Munnu.
