Rajasthan Police Constable Model Paper 5

Statement 1:
X - 15 is a whole number, this shows x can be any integer in the region (-∞, ∞), then we get X as an odd number or an even number,
Thus, we cannot say that whether X + 6 is an odd or even number.
⇒ Statement 1 is not true.
Statement 2:
X - 6 is an odd number, this shows that X is an odd number,
Thus, we can say that X + 6 is an odd number,
⇒ Statement 2 is true.
∴ Statement 2 alone is sufficient to answer the question while statement 1 alone is not sufficient to answer the question.
