A boat having a length 3 m and breadth 2 m is floating on a lake. The boat sinks by 1.8 cm when a man gets on it. The mass of man is
Choose the correct answer:	A) 12 kg	B) 60 kg	C) 108 kg	D) 96 kg	E) none

Rationale: "solution volume of water displaced = ( 3 x 2 x 0.018 ) m 3 = 0.108 m 3 . mass of man = volume of water displaced × density of water = ( 0.108 × 1000 ) kg = 108 kg . answer c"
Answer: C
