It was raining and a water drop accumulated itself over a leaf. It fell down to another leaf and lost 1/4th of its volume. It then fell off to another leaf losing 1/5th of its volume. After that it fell to another leaf losing 1/6th of its volume. This was process was repeated again and again till the water drop reached the last leaf and lost 1/75th of its volume.
Seeking the facts given in the question, will you be able to determine the accurate percentage of loss in the volume of the water drop when it is on the last leaf from its initial volume? Choose the correct choice from the following answers:  A) 5%  B) 3%  C) 8%  D) 4%  E) 9%
D   4%   Suppose that the initial volume of the water drop was p.   p - (1/4) p = (3/4) p   (3/4) p - (1/5) [(3/4) p] = (3/4) p * [1 - (1/5)] = (3/4) p * (4/5) = (3/5) p   (3/75) p = (1/25) p   1/25 = 4%   Therefore, the required percentage is four percent.
