\bold{\huge{\underline{ Solution }}}

Given :-

  • Meena mother is 4 times as old as Meena
  • After 5 years, Her mother will be 3 times as old as she will be then.

To Find :-

  • We have to find the present ages of Meena and her mother.

Let's Begin :-

Let the present age of Meena be ' x ' years.

  • Now, It is given in the question that her mother is 4 times as old as Meena

That means,

Present age of her mother


\sf{ = 4x \: years }

Now,

After 5 years

The age of the Meena will be


\sf{ = x + 5 \: years }

Therefore,

According to given condition,

The age of her mother will be

=
\sf{ = 4x + 5 \: years ...eq(1)}

But, It is given that,

  • After 5 years, Her mother will be 3 times as old as Meena.

That is,

After 5 years, Her mother age will be


\sf{ = 3(x + 5) \: years ...eq(2)}

From eq(1) and (2) :-


\sf{ 4x + 5 = 3(x + 5) }


\sf{ 4x + 5 = 3x + 15}


\sf{ 4x - 3x = 15 - 5 }


\sf{ x = 10 \: years }

Thus, The present age of the Meena will be 10 years.

Therefore,

The present age of her mother will be


\sf{ 4x = 4 × 10 }


\sf{ = 40 \: years }

Hence, The present of Meena and her mother is 10 years and 40 years.
