17 and 14

Explanation:

Let the numbers be a and b

11 is added to the first number, a number twice the second number is obtained
=>a+11=2b ...[A]

If 20 is added to the second number, the number obtained is twice the first number
=>2a=b+20 ...[B]
=>b=2a-20

Put the value of b in the equation [A]
=>a+11=2(2a-20)
=>a+11=4a-40
=>11+40=4a-a
=>51=3a
=>a=51/3
=>a=17
and
=>b=2(17)-20=34-20
=>b=14
