Answers and Explanations


Answer 1: (c)

“Sita is married to Balram” is the correct statement.

Answer 2: (b) 

It is clear that Akbar is the chief. All other options go contrary to the information.

Answer 3: (b)

Let us assume first part of the first statement to be true then second part will be false. If we relate these results with second and then third statements assuming one part to be true and other false. Then we will find that answer is Dhoni. On ‘the contrary if we assume first half of the first statement to be false and second to be true then there will be two answers Ajinkya and Krishna, which cannot be true. Hence the correct answer is Dhoni.

Answer 4: (b)

Option (b) is the only correct statement.
