Question

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. Find their present ages.

Answer 1

Step-by-step explanation:

let present age of Meera =x years

Let present age of Meera's mother =y years

After five years age of Meera =(x+5) years

After five years age of Meera's mother =(y+5) years

According to problem,

y=4x …………..(1)

y+5=3(x+5) ………(2)

Put (1) in (2), we get

4x+5=3x+15

4x−3x=15−5

x=10

y=40

∴ Meera's present age =10 years

Meera's mother's present age =40 years.

Answer 2

Answer:

Meera's age = 10

Meera's mother's age = 40

Step-by-step explanation:

Let Meera's age be $x$

So, Meera's mother's age = 4$x$

After 5 years,

Meera's age = $x$ + 5

Meera's mother's age = 4$x$ + 5

According To Question,

⇒ 4$x$ + 5 = 3 × (

⇒ 4$x$ + 5 = 3

⇒ 4$x$ - 3

⇒ $x$ = 10

∴ Meera's age = $x$ = 10

  Meera's mother's age = 4$x$ = 4 × 10 = 40
