Each of the questions given below consists of a statement and / or a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statement(s) is / are sufficient to answer the given question. Read the both statements and
 Give answer (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.
 Give answer (B) if the 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.
 Give answer (C) if the data either in Statement I or in Statement II alone are sufficient to answer the question.
 Give answer (D) if the data even in both Statements I and II together are not sufficient to answer the question.
 Give answer(E) if the data in both Statements I and II together are necessary to answer the question.
1. 


Answer: Option E Explanation: Given : S.I. = Rs. 50. I gives, R = 10% p.a. II gives, T = 10 years.
Thus, I and II together give the answer. Correct answer is (E). 
2. 


Answer: Option E Explanation: Let the sum be Rs. x. I gives, S.I. = Rs. 7000 and T = 7 years. II gives, Sum + S.I. for 5 years = 2 x Sum Sum = S.I. for 5 years. Now, S.I. for 7 years = Rs. 7000.
Thus, I and II both are needed to get the answer. Correct answer is (E). 
3. 


Answer: Option E Explanation: Let the rate be R% p.a. I gives, P = Rs. 8000 and T = 4 years. II gives, S.I. = Rs. (8800  8000) = Rs. 800.
Thus, I and II both are needed to get the answer. Correct answer is (E). 
4. 


Answer: Option D Explanation:
Now, I gives, S.I. = Rs. 4000. II gives, T = 4 years. But, P is unknown. So, we cannot find R. So, given data is insufficient to get R. Correct answer is (D).
