If 25% of a number is subtracted from a second number the second number reduces to its five-sixths. What is the ratio between the first number and the second number?
Choices: A) 2 : 3 B) 3 : 2 C) 1 : 3 D) Data inadequate E) None of these
Let the first and second number be x and y respectively.   x - y × 25⁄100 = y × 5⁄6   or, y - x⁄4 = 5⁄6y   or, 1⁄6y = x⁄4y   \ x : y = 2 : 3   2 : 3nswer 2 : 3
