P is heavier than T but lighter than M. N is lighter than S and T. Q is heavier than D but lighter than N. S is not heavier than M. The heaviest is Correct Answer M

P is heavier than T but lighter than M.

M > P > T

N is lighter than S and T.

S and T > N

Q is heavier than D but lighter than N.

N > Q > D

S is not heavier than M.

M > S

Combining them we get either

M > S > P > T > N > Q > D

OR

M > P > S > T > N > Q > D

OR

M > P > T > S > N > Q > D

Hence in all the three possible cases M is the heaviest.
