Is A − 5 even? A is a real number.

  1. A − 15 is an integer.
  2. A − 10 is an odd integer.
 A

if statement I alone is sufficient but statement II alone is not sufficient.

 B

if statement II alone is sufficient but statement I alone is not sufficient.

 C

if both statements I and II together are sufficient but neither of statements alone is sufficient.

 D

if each statement alone is sufficient.

Soln.
Ans: b

From statement I, (A − 15) is an integer. So A is also an integer. But A can be even as well as odd. From statement II, if (A − 10) is an odd integer, A will always be odd. Hence, (A − 5) will be even. So only the statement II is sufficient.
