In each of the questions, a question is followed by two statements I and II. Give your answer

Question 145

If numbers x, y, z are all less than 40, how many of them are positive?
I. x + y = 46
II. x + y + z = 80


From statement I we can derive that maximum value of X or Y can have 39 and minimum value of X or Y can have 7.

So,they both are positive but we can't say anything about the value of Z.

From statement II ,we can say that any two of X,Y,Z can have maximum value of 39 then other variable will achieve minimum value of 2.

So,they all are definitely positive.

So, Option B is correct choice.
