GIVEN :Total quantity of coca cola = 90 litres
Replace in a time = 10 litre
Replacement process = 2
FORMULA USED :Final quantity = Initial quantity × (1 – Replacement part)T
Where
T → Replacement process
CALCULATION :Total quantity coca cola = 90 litres
Part of replacement = 10/90 = 1/9 part
In First replacement
Quantity of coca cola which is taken out = 90 × 1/9 = 10 litre
Remaining coca cola = 90 – 10 = 80 litre
Quantity of alcohol = 9 litre
Ratio of coca cola and alcohol = 80 ∶ 10
⇒ 8 ∶ 1
In second replacement
Quantity of mixture which is taken out = 90 × 1/9 = 10 litre
In 10 litre quantity of coca cola which is taken out = (10/9) × 8 = 8.88
Remaining quantity of coca cola in the vessel = 80 – 8.88 = 71.11 ≈ 72 litre
∴ After second replacement remaining quantity of coca cola is approx. 72 litreReplacement part = 10/90 = 1/9
Final quantity of juice = Initial quantity of juice × (1 – Replacement part)T
⇒ 90 × (1 – 1/9)2 ⇒ 90 × 64/81 ⇒ 71.11 ≈ 72 litre
∴ After second replacement remaining quantity of coca cola is approx. 72 litreDownload Solution PDF

When we remove 5- litres of milk or Milk-water mixture, Everytime we remove 10% or the mixture is left with 90% of the milk Present in it.
So after three such operations, the amount of pure milk present in the mixture =
=50 0.9 x 0.9 x 0.9 = 36.45- litres

Since everytime 10% of the solution is removed
( For the first time it says 5 litre solution is removed from 50 litres milk so 5/50 * 100 = 10%)
And the process is repeated 3 times
So
50 *9/10 * 9/10 * 9/10
36.45 L milk is left in the solution

Remaining milk in container: (45*45*45)*50/(50*50*50)= 36.45 litre
Note: 50–5=45. Initial quantity of milk is 50
So when 5 liter is drawn out remaining is 45.
And 5 liter of water is added total is 50, so this process is repeated in another two time which mean all together is three time, so I repeated three time 45/50. Last process in mixture is 50 liter because after added 5 liter of water in mixture there is no taken out

Initially, milk in the container = 50 Litres
Water in the container = 0 L
On removing 5L milk and adding same amount of water,
Milk in the container = 45 L
Water in the container = 5 L
I hope, upto here, it's clear. When again same process is done, 5 L of the solution has been taken out ( We can't say 5L milk will be taken out because that has become a solution now). So if 50 L solution has 45L milk and 5 L water, 5 L solution will have 4.5L milk and 0.5L water
So now, milk in the container = 45–4.5 = 40.5 L
Water in the container = 5–0.5+5 = 9.5 L
The sum of volumes of milk and water should be always

Suppose a container contains X units of a liquid from which Y units are taken out and replaced by water.
After N operations, quantity of pure liquid = X ( 1 - Y / X ) ^ N units
Now, milk exist in the container is = 50 ( 1 - 5 / 50 ) ^ 3
= 50 ( 1 - 1 / 10 ) ^ 3
= 50 * 9/10 * 9/10 * 9/10
= ( 5 * 9 * 9 * 9 ) / 100
= 36.45 liters Naga Prabha
