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.
