Question

6. Meera's mother is four times as old as Meera. After five years, her mother will be three times
as old as she will be then. What are their present ages?​

Answer 1

Answer:

10 and 40

Step-by-step explanation:

Present -

Let the age of Meera be x

Then the age of Meera's mother will be 4x

5 years Later -

Meera's age will be x+5

Mother's age will be 4x+5 or 3(x+5)

By using Equation-

4x+5 = 3(x+5)

4x+5 = 3x+15

     x = 10

So the present age of Meera is 10 years and her Mother's age is 40

Answer 2

Answer:

Let the present age of meera be x years and present age of merra's mother be y years.

It is given in the question that meera's mother is four times as old as Meera :]

➴ y = 4x........(Equation [1])

After 5 years,

Age of meera = (x + 5) years.

Age of merra's mother = (y + 5) years.

➴ (y + 5) = 3(x + 5)............(Equation [2])

Now, Putting equation (1) in equation (2) we get :

➳ 4x + 5 = 3x + 15

➳ 4x - 3x = 15 - 5

➳ x = 10 years

Now, Putting the value of x = 10 in equation (1) we get :

➳ y = 4x

➳ y = 4(10)

➳ y = 40 years

Therefore,

Present Age of meera = 10 years.

Present Age of merra's mother = 40 years.
