    A)  30 litres           

    B)  60 litres

    C)         75 litres

    D)         45 litres

    Correct Answer: A

    Solution :

    Let quantity of water in tank B be X litres. \[\therefore \] Quantity of water in tank A = 5X litres Total water in both the tanks =X+5X = 90 litres \[\Rightarrow \]\[6X=90\] \[\Rightarrow \] \[X=15\] \[\therefore \]Water in tank B = 15 litres  \[\Rightarrow \]Water in tank A \[=15\times 5=75\]litres So, quantity of water to be transferred from tank A to tank B, so that each tank contains 45 litres \[=75-=45\] litres Therefore, 30 litres of water should be transferred.
