Let us assume that the number is = x Then the equation can be written as 25x/100 = 100 25x = 100 * 100 25x = 10000 x = 10000/25 x = 400 So the required number is 100. In this case, understanding the question is of immense importance. Once the words of the problem are converted to numbers, then there is no issue left. It is a straight forward problem otherwise. Hopefully i have explained this problem to you for answering any such problems in the future.
