- c is an even number.

**A**

if 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 data in 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 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**

Using statement I alone, it can't be said definitely which of the integers out of a, b, c, d, e will be odd numbers. However, using statement II with statement I, we can find that if c is even, b and d will be odd.

### 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.

In a class of 60 students, how many boys scored over 90% in the Chemistry test?

**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 II, it is clear that out of 60 students, 40 students scored over 90% in the test . Now it is given in statement I that 5 girls scored over 90%.

Hence, number of boys who scored more than 90% = 40 − 5 = 35.
