36.  Question: How is T related to K? Statements:


Answer: Option E Explanation: From II, we know that T's mother has only two sons, A and B. This implies that T is the sister of both A and B. But, from I, A is also K's son. So, T is the daughter of K. 
37.  Question: What is the shortest distance between Devipur and Durgapur ? Statements:


Answer: Option D Explanation: Clearly, the distance of each village from Rampur is given in I and II. But nothing about their relative positions is mentioned. So, the distance between the two villages cannot be calculated. 
38.  Question: How is A related to D ? Statements:


Answer: Option D Explanation: From I and II, we conclude that A is either son or daughter of D. 
39.  Question: Manoj, Prabhakar, Akash and Kamal are four friends. Who among them is the heaviest ? Statements:


Answer: Option A Explanation: From I, we have: P > M, P > K, A > P. Thus, A > P > M > K or A > P > K > M. So, Akash is the heaviest. From II, we have: P > M, A > M, M > K. Thus, A > P > M > K or P > A > M > K. So, either Akash or Prabhakar is the heaviest. 
40.  Question: Vinod's and Javed's salaries are in the proportion of 4 : 3 respectively. What is Vinod's salary ? Statements:


Answer: Option B Explanation: Statement I is merely an interpretation of the information contained in the question. However, Vinod's salary can be ascertained from II as follows : Let Vinod's and Javed's salaries be 4x and 3x respectively. Then, 3x = 4500 or x = 1500. Therefore Vinod's salary = 4x = Rs. 6000.
