Ans : 65:19
mixed 1 6:1 => 6/7 milk and 1/7 water
mixed 2 5:2 => 5/7 milk and 2/7 water
mixed 3 3:1 => 3/4 milk and 1/4 water
since they are added equally so ,amount of milk in mixture is
[ 6/7 + 5/7 + 3/4 ] = 65/28
and amount of water in mixture is 19/28
so ratio is 65:19

since each container contains equal mixture,so the total amount will be 28litre
as by ratio given ,let 1st vessel contain 7litre(6+1) of mix ,2vessel contains 7litre of mix(5+2),3rd vessel contains 4litre of mix(3+1)
hence for equal mix we take lcm of all mix that comes out to be 28
now,
I II III total
milk 24 20 21 65
water 4 8 7 19
hence the ratio is 65:19
