there is a cask of full of milk . E letter are drawn from the cask it is then filled with water .this process is repeted now the ratio of milk and to water in the cask is 16:9 what is the capacity of cask in the liter..?
Read Solution (Total 5)
-
- 5E
if x is capacity of cask, then
initially
x ltr milk .. 0 ltr water
after first draw and water filling by E ltrs,
x-E ltr milk and E ltr water
after 2nd draw and water filling by E ltrs,
x- [2E-(E^2/x)] and 2E -( E^2)/x ltr water
As per condition
x- [2E-(E^2/x)] /[ 2E -( E^2)/x] = 16/9
solving, we get
x=5E - 11 years agoHelpfull: Yes(13) No(0)
- {(x-e)/x}^2=16/25
x=5e......answer - 11 years agoHelpfull: Yes(2) No(1)
- let total milk = XE ltrs
milk removed frm cask = X-E ltrs
let water added = E ltrs
since the process is repeated;
milk removed =(X-2)E
WATER ADDED = 2E
TOTAL RATIO = (X-2)E/2E=16/9
= X=50/9 - 11 years agoHelpfull: Yes(1) No(5)
- Let cask capacity =XE liters
E liters are dawn from the cask it is then filled with water,
this is two times=XE-2E
Now total (X-2)E lits milk and 2E lits in the cask
Then Ratio of milk and water=(X-2)E/2E=16/9
Then X=50/9
Then the capacity of cask=(50/9)E liters - 11 years agoHelpfull: Yes(0) No(6)
