Solution -
Present age of Avani and Raj are 20 and 30 years respectivelly.
Therefore, their present ration is 2:3
Let us assume, x years ago their age ration is 3:5
Therefore, (20-x) / (30-x) = 3/5
5 (20-x) = 3 (30-x)
100 - 5x = 90 - 3x
2x = 10
x = 5
Answer- 5 years ago, the ration of Avani and Raj were 3:5.

Age of Avani is - 20 - 5 = 15 and Age of Raj is - 30 - 5 = 25
