  • question_answer 22) Four balls A, B, C and D are placed inside a container, one after another. The bar graph shows the weight of the container when empty and when different balls are placed in it. Which ball is the heaviest?

    A)                               

    B)                   

    C)                   

    D)             

    Correct Answer: B

    Solution :

    Weight of an empty container = 80 g Weight of ball A + weight of container = 180 g \[\Rightarrow \]Weight of ball A = \[\left( 180-80 \right)\]g = 100 g Weight of (ball A + ball B + container) = 360 g \[\Rightarrow \]Weight of ball B \[=\text{ }\left( 360-180 \right)\]g = 180 g Weight of (ball A + ball B + ball C + container) =500g \[\Rightarrow \]Weight of ball C \[=\text{ }\left( 500-360 \right)\]g = 140 g Now, weight of (ball A + ball B + ball C + ball D + container) = 580 g \[\Rightarrow \]Weight of ball D \[=\text{ }\left( 580-500 \right)\]g = 80 g So, the ball B is the heaviest.
