Question

Vani's
age
is three times the age
of Meenu. Eight years later vani
will be twice the as Meenu find
their present age.​

Answer 1

Answer:

Step-by-step explanation:

let Meenu 's age be x yrs

so, Vani ' s age = 3x yrs

after 8 yrs vani will be 3x + 8 yrs

after 8 yrs meenu will be x+8 yrs

so ,

⇒3x+ 8 = 2 ( x+8)

⇒ 3x+8 = 2x+16

⇒x = 8

so meenu is 8 years now

and vani is 24 years

hope it helps;)

mark me the brainliest

have a good day!!!!

Answer 2

Answer:

• Vani's present age is 24 years.
• Meenu's present age is 8 years.

Step-by-step explanation:

Given that:

• Vani's age is three times the age of Meenu.
• After eight years, Vani will be twice the age as Meenu.

To Find:

• Vani's and Meenu's present age.

Let us assume:

• Meenu's present age be x.

Then,

• Vani's present age will be 3x.

Eight years later:

• Meenu's age = (x + 8) years
• Vani's age = (3x + 8) years

According to the question:

$\sf{\implies3x+8=2(x+8)}$

Opening the bracket,

$\sf{\implies3x+8=2x+16}$

Transposing variables to LHS, constants to RHS and changing their sign,

$\sf{\implies3x-2x=16-8}$

Subtracting,

$\bf{\implies x=8}$

Hence,

• x = 8

Therefore,

• Meenu's present age = x = 8 years
• Vani's present age = 3x = 3 × 8 = 24 years
