Answer E.
Let's consider two situations that each satisfy both statements together:
If BAD=ADC=90, and ABC=2*BCD, BCD would indeed equal 60.
If DAB=ABC=90, BCD=45 (ABC=2BCD) and ADC=135. No angle would equal 60.

Hi,
the Answer E is correct.
The total of the four angles of the quadriateral is 360 degrees.
If two angles are right angles, i.e. these two sum up to 180 degrees.
Then remaining two would sum upto: 360 -180 = 180 degrees.
If these are in the ratio of 1 & 2 then the angles must be 60 & 120 degrees, viz., one angle is 60 degrees.
Hence Both together are sufficient but not alone.

Hmm. I first thought E as well, but now I think the answer can be C...
from 1) + 2) 180 + x + 2x = 360
3x = 180
x=60 ??
Dose anyone else see this question before and know the answer?
