A certain animal shelter has 26 horses and 36 cows. How many horses must be taken away from the animal shelter so that 75 percent of the animals in the shelter will be cows?  Answers:
A) 12
B) 13
C) 14
D) 15
E) 16
Suppose x horses need to be removed from the shelter.   After x horses are removed, the shelter shall have (26 - x) horses and the same 36 cows; and the total number of animals shall be (26 - x) + 36 = 62 - x   Now we want the 75 percent of animals in the shelter to be cows.   This means 75 percent of (62 - x) should be equal to the number of cows which is 36.   This means,   75 % of (62 - x) = 36   Solving above equation we get x = 14   x=14   Ans 14
