The ratio of the current ages of Ajay and Vijay is 7:4. The ratio between Ajay's age 6 years ago and Vijay's age 6 years from now is 1:1. Find the ratio between Ajay's age after 12 years and Vijay's age 12 years ago.
correct answer b
Let the current age of Ajay and Vijay be 7x and 4x respectively.
`(7x – 6) / (4x + 6) = 1/1`
7x – 6 = 4x + 6
3x = 12
x = 4
Therefore, `(7x + 12) / (4x – 12) = (7**4 + 12) / (4 ** 4 -12) = 40/4 = 10/1`
