    Vishnu has two plastic bottles of different shapes. The two bottles are connected through a pipe, as shown in the given figure. Initially, both the bottles have water up to an equal level. One of the bottles has a tap. Vishnu opens the tap for some time such that the water level in bottle II decreases by one centimetre. The initial water level in each bottle is seven centimetres. What is the new water level in bottle I?

    A)  5.5 cm                 

    B)  6.0 cm

    C)  6.5 cm                 

    D)  7.0 cm

    Correct Answer: B

    Solution :

      It is given that the water column in bottle II is decreased by 1 cm. Therefore, the water column in bottle I will also decrease by 1 cm. Hence, the new water level in bottle I is (7 - 1) cm = 6 cm. The correct answer is B.
