Answer 1

`\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.
