Answer for 1 is E.

Answer for 2 is A.

I haven't solved it through a proper mathematical way. I tried putting down values of few powers of 11 and 5 and spotted a trend. If you want I can try to explain that.

answer to first should be E.
Explanation - when you calculate 11^2, 11^3..and so on..you will observe that 4 will appear at the tens place after every 10 such calculations..i.e. at 11^4, then at 11^14..and so on..similarly with 5, 6 appears at the hundredth place at every alternate power..i.e. at 4, 6, 8..
so both the statements are not sufficient to answer the question..

similarly the answer to second is A
