Solutions:
1. None of the groups help us reach a conclusion. From option a, the conclusion H is violated through the flow of the other statements which suggest that water level in the coastal areas will rise. In option b, we know that people will change their lifestyle and so, the temperature will not rise. However, statement D is in the form of p -> q and so, we can only say that ~q -> ~p. None of the other statements are in this form and so, a conclusion cannot be reached. Option c suffers from the same flaw as option b. So option d is correct.
2. Statement F says that Kumar sings only if Vina dances. However, Vina dances does not necessarily mean that Kumar sings. It simply means that Kumar is eligible to sing and nothing else. So, option a is not logically conclusive. Option b talks about audiences sleeping. Now, sleeping cannot be said to be ‘not dancing’ as it has not been explicitly mentioned. Option c is perfect as it has a nice EG link and we can reach a logical conclusion.
3. From the statements of A, we do not get any information about C. So, we cannot be sure if A has spoken the truth. Similarly, B does not tell us the status of A and so, we cannot be sure if B is telling the truth. In case of the statements by C, we are unable to figure out the gender of B and C. In case of D, we know for sure that the couple is BC and that C has to be the son of D. So, D is always true.
4. B is the wife of C. Option c.
5. Option d. A has lied in both the statements.
6. 343 – 49 – 36*2 – 6 = 216. Option d.
7. 127 – 19 = 108 cubes. Option a.
8. All cubes except the one in the front upper corner. So, 342 in total. Option b.
9. B only. Option b.
10. 1 km to the east. Option c.
