Answer 2

Answer:

40 years is Radha's present age.

Step by Step explanation

Let present age of her daughter be x

Then, age of Radha will be 4x

After 20 years,

Her mother's age will be: 4x + 20

Radha's age will x + 20

Now, A.T.Q:

4x + 20 = 2(x + 20)

2(2x + 10) = 2(x + 20)

2x + 10 = x + 20

2x - x = 20 - 10

x = 10

Therefore, Her daughter's age is 10 years.

Radha's age = 4x = 4 × 10 = 40 years

Thus, the present age of Radha is 40 years.
