Q. The sum of two numbers is equal to the thrice of their difference. What will be the ratio between them?

  • (A) 1 : 3
  • (B) 3 : 1
  • (C) 1 : 2
  • (D) 2 : 1
Correct Answer - Option(D)
Explanation by: Ravi Chauhan 
Let the numbers be 'a' and 'b'. According to the question -
(a + b) = 3(a - b)
(a + b) = 3a - 3b
2a = 4b
a = 2b
So, a/b = 2 : 1
