(A)30 litres
(B)60 litres
(C)75 litres
(D)90 litres
Ans 1:
Class : Class 8
The answer is 30 litres(a).
Tank A: 45+30=75
Tank B:75/5=15
so the water transferred from Tank A to tank B so that each tank contains 45lit of water should be 30 litres [Tank A: 75-30=45; Tank B: 15+30=45]
Ans 2:
Class : Class 6
Quantity of water in tank A= 5x
Quantity of water in tank B= x
Total quantity of water= 6x
6x=(45+45) litres
6x= 90 litres
x=15 litres
A=5X=75 LITRES, B=15 LITRES
Quantity of water transfered from A to B=30
