सही उत्तर: क) The statements together are sufficient, but neither alone is
Neither alone fixes x + y. Together, x + y = (x² − y²)/(x − y) = 32/4 = 8.

Data sufficiency. What is the value of x? (1) x² = 9. (2) x > 0. Which is true?

Data sufficiency. Is the integer x even? (1) x + 3 is odd. (2) 2x is even. Which is true?
सही उत्तर: घ) Statement (1) alone is sufficient, but statement (2) alone is not
(1): if x + 3 is odd, x must be even, so it is sufficient. (2): 2x is even for every integer x, so it tells nothing.
