Question

Smita is twice old as vinita .The sum of their ages is 24
How old is Vinita?

Answer 1

Answer:

Age of Vinita = x years

Age of Smita =2x years

A/q, x+2x = 24

3x = 24

x = 24 ÷ 3

x = 8 years

Value of x = age of Vinita .

So, Age of Vinita =8 years and,

age of Smita = 2x years = 2×8 years = 16 years

Answer 2

Step-by-step explanation:

Let the age of smita be x and Vinita be y

ATQ

x=2y

x-2y=0

Also,x+y=24

x+y-24=0

x+y=24

Using elimination method,

x-2y=0

x+y =24

- - -

__________

-3y=-24

y. =-24/-3

y=8

So vinita present age is y=8
