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.

Balwinder scored an average of 60 marks in English, Mathematics and Computer. How much did he get in Mathematics?

- His average score in English and computer is 45.
- He got 40 marks in Computers.

**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 even in both the statements together are not sufficient to answer the question.

**Soln.**

**Ans: a**

As given in the question, his total marks E + M + C = 180. From statement I, we get E + C = 90. From here his marks of Mathematics are known. Therefore, statement I alone is sufficient to answer the question. Statement II alone is not sufficient because from this C = 40 which can't help us to know the marks of Mathematics.
