Answer: (4) 15 years 

Explanation:-
The age of Adam = 20 years

Adam is 4 times as old as Mary.
Then, the age of Mary = 20/4
 = 5 years

If the age of Adam is  20 + 10
 = 30 years
Then, the age of Mary is 5 + 10 = 15 years. 

Thus, Mery will be 15 years old when Adam is twice as old as her. 

Hence, the correct answer is option (4) 15 years.
