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

Ans 2:

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]
