Question: If a vessel contains 56 lit of a mixture of milk and water in ratio3:2.what amount of the water should be added to make the ratio 4:5 ?

Answer: 3:2 = 56 lt
1 x = 56/(3+2)=>56/5=>11.2
therefore, (11.2x3) + (11.2x2) =>33.6+22.4 => 56
now,
4:5 = 33.6 : ? => ?=(33.6x5)/4
=> ? = 42
Now we want (42-22.4) = 19.6 lt more water to make a ratio of 4:5

19.6
mixture contains 56 lit.
water =(2/3+2)*56=22.4
milk=(4/9)x=33.6.
where x represents total litre.
x=75.6.
total amt of water=(5/9)x.
total amt of water=42.
additional water=42-22.4=19.6lit Source: CoolInterview.com

milk/water=3x/2x
3x+2x=56
x=11.2
now 3x/(2x+y)=4/5
y=19.6 litres Source: CoolInterview.com

Total quantity=56 liters.
Let x be the no of lit. of extra water added to become the milk & water ratio as 4:5.Then
and 33.6 & 22.4 be the milk & water in the 56 liters of water respectively then.
(4/5)=(33.6/(x+22.4)
Then we will get,
x=19.6. Source: CoolInterview.com

Let x litre of water be required,
initial volume of milk=3/5*56
after adding water-
total volume=56+x
now volume of milk=4/9*(56+x)
but the volume of milk should be equal in both case
3/5*56=4/9*(56+x)
on solving-
x=19.6lts Source: CoolInterview.com
