Equal quantities of three mixtures of milk and water are mixed in the ratio 1:2, 2:3 and 3:4. The ratio of water and milk in the mixture is:

Select one:
a. 193:122
b. 61:97
c. 137:178
d. 122:193

• d)122:193
  solution
  
  (1:2),(2:3),(3:4)
  (1+2),(2+3),(3+4)
  3,5,7
  equal quantities of mixture i.e. lcm of 3,5,7=105
  105/3=35 , 105/5=21 , 105/7=15
  (35*1,35*2),(21*2,21*3),(15*3,15*4)
  (35,70),(42,63),(45,60)
  so overall mixture ratio is
  35+42+45:70+63+60
  122:193

• 122:193
  
  Let the total content be x
  
  Volume of milk in final mixture = (x/3)+(2x/5)+(3x/7)
  Volume of water in final mixture = (2x/3)+(3x/5)+(4x/7)
  
  By dividing the above two equations, we will get answer as 122:193
