Question

Anita's mom is four times Anita age. 20 years later she will be twice as Anita's age . Find Anita present age

Answer 1

From the given data:

Anita : x

Anita's mom: 4x

After 20 yrs

Anita: x + 20

Anita's mom: 4x + 20

Therefore

2(x + 20) = 4x

2x+40 = 4x

40 = 4x - 2x

40 = 2x

x = 20

Anita's age is 20

Answer 2

Let Anita's age be x

mother's age=4x

after 20 years

Anita's age= x+20

mother's age= 4x+20

According to the question

2(x+20)=4x+20

2x+40=4x+20

40-20=4x-2x

20=2x

x=20/2

x=10

Anita's age= x=10
