Question: What is the code for 'sky' in the code language ?
Statements:
- In the code language, 'sky is clear' is written as 'de ra fa'.
- In the same code language, 'make it clear' is written as 'de ga jo'.

Question: How many children are there between P and Q in a row of children ?
Statements:
- P is fifteenth from the left in the row.
- Q is exactly in the middle and there are ten children towards his right.
From II, Q being in the middle, there are 10 children to his right as well as to his left. So, Q is 11th from the left. From I, P is 15th from the left.
Thus, from both I and II, we conclude that there are 3 children between P and Q.
Question: How is T related to K?
Statements:
- R's sister J has married Ts brother L, who is the only son of his parents.
- K is the only daughter of L and J.
From I, we know that L is T's brother and J's husband. Since L is the only son of his parents, T is L's sister.
From II, we know that K is L's daughter.
Thus, from I and II, we conclude that T is the sister of K's father i.e. T is K's aunt.
Question: How is J related to P ?
Statements:
- M is brother of P and T is sister of P.
- P's mother is married to J's husband who has one son and two daughters.
