# Data Sufficiency Quiz Set 006

### Question 1

You have to decide whether the data provided in the statements are sufficient to answer the question. Read the statements and give your answer.

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.

### Question 2

The following question consists of a question followed by two statements labeled I and II. You have to decide whether the data given in the statement (s) is /are sufficient for answering the question.

The sum of ages of M, N, and O is 50 years. What is N's age?

C

if data either in statement I alone or in the statement II alone are sufficient to answer the question.

D

if data in both the statements I and II together are needed to answer the question.

Soln.
Ans: d

As given in the question, M + N + O =50 years. Combining statements I and II, we get N = 15 years, M = 5, and O = 30.

### Question 3
