D 1/4 of 2400 is 600. 1/4 of 600 is 150. So the total number of primates after reduction is 600150=450 and the total number of animals is 2400150=2250. 450/2250=0.2

Hi SajjadAhmad, The answer choices to this question are written in such a way that you can avoid doing math altogether and just use a bit of logic to answer this question. To start, we know that 1/4 = 25% of the animals are primates. Once we remove some of the primates, the percent of the total that will be primates will be something LESS than 25%  which means that the answer would have to be either D or E. Since we're only removing 1/4 of the primates, the drop in percent won't be gigantic, so the only answer that makes sense is... Final Answer: GMAT assassins aren't born, they're made, Rich

A. 50% B. 33 % C. 25% D. 20% E. 6.25% no. of primates = 1/4*2400 = 600 new no of primates after reduction = 600*3/4 = 450 total number of animals = 2400150 = 2250 percentage = 450/2250 x 100 = 20% option D

2400/4 = 600 primates total
600 primates/4 = 150
Reduce the total primates by 150: 600 primates 150 primates 450 primates left
Reduce total animals by 150: 2400 animals  150 primates 2250 animals left
Now find percent primates out of total animals: 450 remaining primates = 9 = 1 2250 remaining animals 45 5
1/5 = 20% > D
