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#
