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
Read Solution (Total 3)
-
- 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 - 8 years agoHelpfull: Yes(3) No(0)
- 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 - 8 years agoHelpfull: Yes(2) No(0)
- 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 - 9 years agoHelpfull: Yes(0) No(1)
