Question 9

# A vessel has 500 litres of milk. 50 litres of milk is replaced with 50 litres of water in this vessel. If this operation is repeated another 2 more times, whatis the percentage of milk in the vessel at the end?

Solution

We have formula :
F = $$I\left(1-\frac{K}{\left(V\right)}\right)^n$$
Here n =3 V =500 k =50
substituting we get
F/I = 729/1000
Therefore in percentage F = 72.9 percent
