There are two numbers , 1 st number is 12 more than the 2nd number . The average of the two numbers is 19. If 2 is added in both numbers , find the ratio of the numbers .

  • A. 5 : 9
  • B. 5 : 9
  • C. 5 : 9
  • D. 5 : 9

Answer: Option D

Explanation:

ATQ,
x - y = 12
x + y = 38
.......................
2x = 50 (Adding the equations)
Or, x = 25
So, y = 13 Then, if 2 is added in both numbers , find the ratio of the numbers = x + 2/y + 2 = 27/15 = 9/5
