Question

a greedy milkman sells milk by adding 20% of water for every 1 litre in order to make more money he further mixes 10% more water what is the total percentage of water that he mixes​

Answer 1

Answer:

the answer is 320 ml

He add 20% water for every 1 litre milk (for every 1 litre not in every 1 litre)..

20%of 1000 ml( 1 litre)

200 ml

Now total is

1000±200= 1200ml

He also added 10% more water in it rather than.

10% of 1200ml=120ml

Now total solution is 1200+120=1320ml

As we know he have only 1 litre milk

Then

Water =Total - Milk

Water=(1320-1000)ml=320ml

So there he add now 320 ml water for every 1 litre milk
