what will be the ratio of petrol and kerosene in the final solution formed by mixing petrol and kerosene that are present in three vessels in the ratio 4:1, 5:2, 6:1 ?

1) 166:22
2) 83:22
3) 83:44
4) None of these

• We have to find the ratio of petrol and kerosene in the final mixture,
  Quantity of petrol = 4/5 + 5/7 + 6/7= 83/22
  Quantity of kerosene= 1/5+ 2/7+ 1/7
  =22/35
  Petrol : kerosene = 83:22
  Option (b) is correct

• Take a ratio of final mixture,
  Then 4/5+5/7+6/7=83/35
  1/5+2/7+1/7=22/35
  Ans.83:22

• 2) 83:22
  
  Since vessels are of equal capacity
  therefor taking a,b,c as the factor of corresponding ratios
  we get
  5a=7b=7c
  
  now we are to calculate total ratio
  total petrol/ total kerosene
  
  (4a+5b+6c)/(a+2b+c)
  using the relation 5a=7b=7c
  we can calculate it
