Question
The ratio of the sum of two numbers and their difference is 5:1. The ratio of the greater number to the smaller number is___________
A. 5:1
B. 2:3
C. 1:5
D. 3:2
Answer: D
Solution:
Let the numbers be x and y.
We know that x + y/ x – y = 5/1
=> 5x – 5y = x + y
=> 4x = 6y
=> x/y = 6/4
x : y = 3 : 2
