# Data Sufficiency Quiz Set 016

### Question 1

The problem below consists of a question and three statement I, II and III given below it. Read all the statements carefully and see all possible combinations which could be sufficient for answering the question. A single statement or statements with least combinations which could be sufficient for answering the question would be your answer.

A

I and II only.

B

I and III only.

C

II and III only.

D

I only.

Soln.
Ans: b

Statement II is not required to know the youngest among Guddu, Prashant, Karan and Jasveer.

### Question 2

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

A's salary was increased by 20%, by what % his savings is increased ?

1. He used to save 10% of his income before increment.
2. He increased his expenses just by 10% after increment.
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: c

If we suppose the income to be Rs 100, then from statement I, A spends Rs 90 and saves Rs 10. From statement II, his expenses now become 99. Therefore, savings as becomes 120 − 99 = Rs 21. Hence, A's saving is increased by Rs 11 i.e., 110%.

### Question 3

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

Among Baldeep, Suresh, Narinder, Param and Karan, who has secured maximum marks in mathematics?

1. Karan has secured more marks in Mathematics than Suresh and Narinder.
2. Baldeep and Param have secured less marks in Mathematics than Narinder.
A

if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

B

if the data in the statement II alone are sufficient to answer the question while the data in statement I alone are not sufficient to answer the question.

C

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

D

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

Soln.
Ans: d

∴ Karan secured maximum marks. Hence, the answer of the question can be known from I and II together.

### Question 4

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

Which of the following means 'very' in a certain code language?

1. 'pit jo ha' means 'very good boy' in that code language.
2. 'jo na pa' means 'she is good' in that code language.
A

if the data in statement I alone are sufficient to answer the question, while the data in statement II alone are not sufficient to answer the question.

B

if the both in the statement II alone are sufficient to answer the question while the data in statement I alone are not sufficient to answer the question.

C

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

D

if the data given in both the statements I and II together are not sufficient to answer the question.

Soln.
Ans: d

Data given in both the statements are not sufficient to solve the question because the code for 'very' is either 'pit' or 'ha'.

### Question 5

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

What are the sides of a right-angled triangle ?

1. The difference between the hypotenuse and base is 6 cm.
2. The difference between the hypotenuse and perpendicular is 3 cm.
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: c

From statement I, H − B = 6 and from statement II, H − P = 3. Now we know that in right angle triangle H ² = P ² + B ². By solving these three equations, sides of triangle can be known. Hence, both the statements are required to answer the question.
