Question

Given, Munnu’s age to be $x$ years. Can you guess what \[\left( {x{\text{ }} - {\text{ }}2} \right)\] may show? Can you guess what $(x + 4)$ may show? What $(3x + 7)$ may show?

Answer 1

Hint- In order to deal with this issue we are going to keep the present age of munnu as a guide further whatever we have to guess we are going to equate his / her age with the problem, just like this we can guess all over the problem.

Complete step-by-step answer:
Provided the age of Munnu = $x$ years
It is observed that $(x - 2)$ is an age smaller than $x$ because here 2 years from Munnu 's age are subtracted
So, $(x - 2)$may be the age of a younger brother of Munnu
Again for years $(x + 4)$ it is clearly observed that $(x + 4)$ is an age greater than $x$, since here 4 years are included in the age of Munnu
So, $(x + 4)$ may be an elder sister of Munnu 's generation.
At last $(3x + 7)$ is an age very bigger than Munnu's age because here firstly Mummy's age is multiplied by $3$ and further added by $7$years
So $(3x + 7)$ can be the age of Munnu's father.

Note- An application of linear equations is what are called age problems. When we are solving age problems we generally will be comparing the age of two people both now and in the future (or past). Using the clues given in the problem we will be working to find their current age.
