out water from the can. If the cans had capacities 8 and 6 litres respectively,
could you collect 5 litres?​

Answer 1

Step-by-step explanation:

First fill the 9 Lt can completely And pour it into the 5 litre can and then empty the 5 Lt can

now you are left with 4 Lt water in 9 Lt can

pour this 4 Lt water in 5 Lt can

now there is 1 Lt capacity left in 5 Lt can

completely fill the 9 Lt can and transfer 1 Lt from 9 Lt can to 5 Lt can

Empty the 5 Lt can and then you are left with 8 Lt water in the 9 Lt can

pour this 8 Lt water in 5 Lt can and you can get the 3 Lt water required

nope the other case is not possible
