Answer 1

Annyeonghaseyo BTS ARMY!!!! Here is your answer-

You say Corbyn, a guy has a can with 9 litres of milk. He takes out 3 litres from it, so amount of milk left in the can is now (9-3) litres = 6 litres.

He adds 3 litres of water now. So, the amount of mixture again becomes (6+3) litres = 9 litres. He mixes them well, and takes out another 3 litres of the mixture, leaving 6 litres again.

So, amount of water is 3 litres and milk is 3 litres. If he adds another 3 litres of water, the amount of water becomes 6 litres i.e. (3+3) = 6 litres.

So, the ratio of milk to water is = 3 : 6.

Hope it helps.
