Q) Two containers of equal capacity are full of mixture of oil and water.In the first the ratio of oil to water is 4:7 and in the second it is 7:11. Now both the mixture are mixed in a big container.what is the resulting ratio of oil to water?
Thanks,
Ashish
lets say each container had capacity of x
volume of oil in first = 4x/(4+7) = 4x/11
Volume of water = 7x/11
In the second container
volume of water = 11x/18
volume of oil =7x/18
So total volume of oil = 7x/18 +4x/11
Volume of water = 11x/18 + 7x/11
So ratio = ...go ahead
