Question

meera's is now 10 year older than her twin brother. after 3 years from now, thrice her age will be four time the sum of her age brother's age than find meera's peasant age ​

Answer 1

Step-by-step explanation:

Let the age of Meera be x.

Let the age of her twin brothers be y.

Given that Meera is now 10 years older than her twin brothers.

x = y + 10 ----- (1)

 

3 years hence:

The age of Meera = x + 3.

The age of her twin brother = y + 3.

Given that 3 years from now, thrice her age will be 4 times the sum of her brother's age ago.

3(x + 3) = 4(2(y + 3)

3x + 9 = 4(2y + 6)

3x + 9 = 8y + 24

3(y + 10) + 9 = 8y + 24

3y + 30 + 9 = 8y + 24

3y + 39 = 8y + 24

3y = 8y + 24 - 39

3y = 8y - 15

3y - 8y = -15

-5y = -15

y = 3

Substitute y = 3 in (1), we get

x = y + 10

x = 3 + 10

x = 13.

Therefore the present age of Meera = 13 years.

Answer 2

Answer:

Step-by-step explanation:

Let the age of Meera be x.

Let the age of her twin brothers be y.

Given that Meera is now 10 years older than her twin brothers.

x = y + 10 ----- (1)

3 years hence:

The age of Meera = x + 3.

The age of her twin brother = y + 3.

Given that 3 years from now, thrice her age will be 4 times the sum of her brother's age ago.

3(x + 3) = 4(2(y + 3)

3x + 9 = 4(2y + 6)

3x + 9 = 8y + 24

3(y + 10) + 9 = 8y + 24

3y + 30 + 9 = 8y + 24

3y + 39 = 8y + 24

3y = 8y + 24 - 39

3y = 8y - 15

3y - 8y = -15

-5y = -15

y = 3

Substitute y = 3 in (1), we get

x = y + 10

x = 3 + 10

x = 13.

Therefore the present age of Meera = 13 years.
