A container has 40L milk. 4L milk is taken out and replaced with water, the process done three times. What is the amount of milk now left?  Choose the correct choice from the following choices:
A) 29.16L	B) 29.19L	C) 29.12L	D) 29.11L	E) 29.14L
Explanation:   In regard to the problem let after n times liquid in the container is x and liquid removed is y   =&gt;Liquid in container= x   =&gt;Liquid removed= y   29.16Lfter one trial, quantity of pure liquid= x- (1-y/x)   29.16Lfter n trials quantity of pure liquid = x - (1 -y/x)n   Therefore, Putting the values ( x = 40L y = 4L N=3) and solving   =&gt; 40- (1-4/40)3   = 29.16L   29.16LNSWER:29.16L
