In a certain code language,
A = B means ‘A is the father of B’
A + B means ‘A is the sister of B’
A @ B means ‘A is the wife of B’
Based on the above, how is N related to M if N @ K = L + T = U + M ?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Paternal grandmother.
If N @ K = L + T = U + M → N is the wife of K, K is the father of L, L is the sister of T, T is the father of U and U is the sister of M.

Thus, N is the Paternal grandmother of M.
