Question
X @ Y means X is the sister of Y, X # Y means X is the
mother of Y and If X * Y means X is the father of Y, then what does H * I @ J # K mean?Solution
On decoding ‘H * I @ J # K’ means H is the father of I, I is the sister of J, and J is the mother of K. Drawing the family tree diagram as per the given information. 
Therefore, the above family tree diagram clearly shows that ‘H is the grandfather of K’. Hence, option (D) is the correct answer.
