Alligation or Mixture problems
The ratio of milk to water is 5:4. If two litres of water is added, the ratio becomes 10:9, then find the new amount of water in the mixture.
Let initial quantity of milk & water in the mixture are 5x & 4x 2 litres water is added. Hence, New quantity of milk & water will be 5x & (4x+2) ATQ, 5x/(4x+2) = 10/9 x/(4x+2) = 2/9 9x = 8x + 4 x=4 Hence, New amount of water in the mixture = 4x+2 = (4*4) + 2 = 18 litres.
