Question

Reema's mother is four times as old as Reema. After 5 years her mother will be 3 times as old as she will be then. find their present ages​

Answer 1

Step-by-step explanation:

Let the age of Reema be x.

Hence the age of Reema's mother will be 4x.

After 5 years their ages will be (x+5) and (4x+5).

According to Question:

=> 3(x+5)=4x+5

=> 3x+15=4x+5

=> 3x-4x=5-15

=> -x=(-10)

=> x=10

So present age of Reema is 10 years.

Her mother's age is 4×10 = 40 years.

Answer 2

Answer:

Age of Reema = 10 years

Age of Reema's mother = 40 years

Step-by-step explanation:

Let the present age of Reema be x years and her mother's present age be 4x years.

Then,

After 5 years:

Reema age = (x+5) years

Reema's mother age = (4x+5) years

A/q

4x+5 = 3(x+5)

4x+5 = 3x+15

4x-3x = 15-5

x = 10

Hence, age of Reema = x years = 10 years

and age of Reema's mother = 4x years = (4×10)years = 40 years
