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.You need to login to perform this action.
