A boat having a length 3 m and breadth 2 m is floating on a lake. The boat sinks by 1 cm when a man gets on it. The mass of the man is: Choose the correct choice from the following choices
A) 65 kg	B) 62 kg	C) 120 kg	D) 60 kg	E) 50 kg
Volume of water displaced	= (3 x 2 x 0.01) m3   = 0.06 m3.   Mass of man	= Volume of water displaced x Density of water   = (0.06 x 1000) kg   = 60 kg.   ANSWER 60 kg
