Answer: Paul will be 30 years old

Step-by-step explanation:Let the age of her sister be x, then from the given data

=> 4x = 20

=> x = 5 years

The age of her sister is 5 years

In the second case, paul is twice as old as his sister

=> Age of paul = 2(x)

=> Age of paul = 10 years

Paul will be 10 years old when he is twice as old as his sister

Answer:

Paul will be 30 years old.

Step-by-step explanation:

Paul's sister's age is 1/4 of 20. 20 * 1/4 = 5 years.

Age difference between the siblings : 20 - 5 = 15 years.

That means that Paul will still be 15 years older when he'll be twice the age of his sister.

15 * 2 = 30 years.
