Question

Ranu mother is four times as old as Ranu after 5 years her mother will be three times as old as she will then be find their present age ​

Answer 1

Answer:

hey here is your answer

Step-by-step explanation:

let Ranu's age be x

therefore, Ranu's mother's age = 4x

after 5 years

ranu's age = x+5

ranu's mother's age = 4x+5

According To Question,

    4x+5 = 3(x+5)

    4x+5 = 3x+15

    4x-3x = 15-5

    x = 10years (Ranu's present age)

    4x = 10 × 4 = 40years(Ranu's Mother's present age)

hope this helps you :)

Answer 2

$\bf{\underline{Given}}:-$

• Renu's mother is four times as old as Renu.

• After 5 years her mother will be three times as old as she.

To find :-

• Their present ages

Solution :-

Let Renu's present age be x

and Her mother's age be 4x

⪼ After 5 years,

• Renu's age will be (x + 5)

• Her mother's age will be ( 4x + 5)

According to the Question,

⤇ 4x + 5 = 3(x + 5)

⤇ 4x + 5 = 3x + 15

⤇ 4x - 3x = 15 - 5

⤇ x = 10

Her mother's age = 4x

Her mother's age = 4 × 10

Her mother's age = 40

Hence,the present age of Renu will be 10 years and present age of Her mother's will be 40 years.
