Marbles
Weight (in g)
660
600
540
A) 150 g
B) 280 g
C) 180 g
D) 240 g
Correct Answer:
C
Solution :
Weight of ++ = 540 g Weight of + + = 600 g \[\Rightarrow \]Weight of + (540 - Weight of = 600 \[\Rightarrow \]Weight of = 600 - 540 + Weight of \[\Rightarrow \]Weight of 60 + Weight of Also, Weight of = 660 g \[\Rightarrow \]Weight of + (60 + ) + (60 + )) = 660 g \[\Rightarrow \]Weight of 3 + 120 = 660 g \[\Rightarrow \]Weight of 3 =(660 - 120) g = 540 g \[\Rightarrow \]Weight of = \[\left( 540\div 3 \right)\]g = 180 g
