There are two numbers. If 30% of the first number is added to the second number, then the second number increases to its five-fourth. What is the ratio of the first number to the second number?
Pick
A) 3 : 25
B) 25 : 8
C) 8 : 5
D) 5 : 6
E) 7 : 2
Let the two numbers be x and y.   (3/10) * x + y = (5/4) * y   (3/10) * x = (1/4) * y   x/y = 10/12 = 5/6   The answer is 5 : 6.
