three vessels contain equal mixture of milk and water in the ratio 6:1,5:2 &3:1.if all the solutions are mixed together,the ratio of milk to water in the final mixture will be

• 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
