Answer 1

Answer:

D

if x is more than 20 , then u is negative

may be one of best option

Answer 2

Answer:

D: If x is more than 20, then y is negative.

Step-by-step explanation:

It is not always necessary that both the numbers x and y should be equal, so it is not " Definitely" right. Then,it is also not known that both x and y are positive integers, since the question gives us no scope about this, and one can be a negative integer and the other one a positive integer, so there is also a possibility that x or y might be greater than 20.

Hence, the most appropriate option is D, since x can be more than 20 only if y is negative.

This is DEFINITELY right.
