A boat having a length 3 m and breadth 2 m is floating on a lake. The boat sinks by 1cm when a man gets on it. The mass of the man is:	Select the correct option:
A) 12 kg
B) 60 kg
C) 72 kg
D) 88 kg
E) 96 kg

Rationale: "volume of water displaced = ( 3 x 2 x 0.01 ) m 3 = 0.06 m 3 . mass of man = volume of water displaced x density of water = ( 0.06 x 1000 ) kg = 60 kg . answer : option b"
Answer: B
