Qn 1:

From stmt 1, y could be any values for ex 2*3=6 or 3*2=6 so insuff.
From stmt 2, we do not have any values for x so insuff.
Combing x can be any values between -4 and -5 which means y could also take any value to maintain xy=6 hence insuff.

So E.

Qn 2:
E.

Qn 3. um of 8 wrestlers = 1120
Sum of 10 wrestlers = 1430
Sum of 8 wrestlers + 2 new wrestlers = 1430
2 new wr = 310
