There are two numbers. If 20% 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?
Choose the correct answer
A) 2 : 9
B) 3 : 8
C) 8 : 5
D) 5 : 4
E) 7 : 3
Let the two numbers be x and y.   (2/10) * x + y = (5/4) * y   (2/10) * x = (1/4) * y   x/y = 10/8 = 5/4   The answer is 5 : 4.
