Question

From a vessel initially filled with pure milk every time one-tenth part of it is withdrawn and an equal amount of water is added to the vessel .How many times the process is to be contained in order to make the bucket

Answer 1

Answer:

Let pure milk was 100L. So,

Water is replaced 20% in per process = 20% of 100 = 20L.

Now, we use short-cut formula for it.

Quantity of Milk reduced to,

=X×[1−YX]n=100×[1−20100]3=100×64125=51.2%

Here,

X = Initial quantity of milk.

Y = Replaced water in per process.

n = No. of process repeated.
