Only one person got lower rank than K’s daughter-in-law.
Q is the sister-in-law of O and vice-versa.
Q is the only daughter of K.
O doesn’t have any siblings.
That means, O must be daughter-in-law of K.
K got higher rank than both L and M but not as much as P, who didn’t get the highest rank.
Based on the above given information we have:For Ranking:
__ P > K > L, M
Again, we have:
N is the only daughter of L, who got three ranks higher than N.
Q is the paternal aunt of P, who got immediate lower rank than Q.
From the above given statement we have:
Q > P > K > L, M
Again, we have:
Q’s daughter got immediate higher rank than L’s wife.
L is not married to K.
That means, L must be married to O.
Since, M is the only remaining person, thus M must be daughter of Q.
The gender of K and M is not same.
Thus, K must be the father of Q.
Based on the above given information we have:
