Question

Rohit's sister is 4 years younger to him. He got married 10 years back and his present age is 4/3 times his age at the time of marriage. Find the present age of his sister?

Answer 1

The given question is Rohit's sister is 4 years younger to him. He got married 10 years back and his present age is 4/3 times his age at the time of marriage. Find the present age of his sister?

let the age of rohit be x and his sisters age be x-4

because his sister is 4 years younger than him.

He got married 10 years ago

so his age will be reduced by 10

now rohit age will be (x-10).

It's said that rohits present age is 4/3 times of his age at the time of marriage.

$x = \frac{4}{3} (x - 10)$

$3x = 4x - 40 \\ 4x - 3x = 40x = 40$

The present age of rohit is 40.then his sisters age is x-4 which was 40-4=36.

The present age of his sister is 36

Answer 2

His Sister's Present Age is 36 Years Old.

Approch:

In order to determine Rohit's sister's age, we would:

• Recognize and identify the timing points in the questions
• We would be able to frame Rohit's age in a linear equation.
• We would determine Rohit's sister's age after evaluating his age.

Let, Rohit's Present Age be  $" x "$

Now,

Rohit's marriage took place 10 years back from now.

i.e. age would have been reduced to $[ x - 10 ] years$

In addition, on comparison of his current age to that at the time of marriage, the question states:

$Present\ age\ of\ Rohit\ = \frac{4}{3} \times Age\ when\ he\ got\ Married$

Then according to the problem,

$x = \frac{4}{3} \times (x-10)\\\Rightarrow 3x = 4x - 40\\\Rightarrow x=40$

Now we have Rohit's Present age, i.e. x = 40 years.

Since, His Sister is 4 years younger than him, at present

Therefore,

His Sister's Present Age is = [40-4] = 36 Years Old
