0.1 decates ago, Vijaya was quadrice as old as her daughter Simran. 0.6 decades hence, Vijayas age will beat her daughters age by 0.9 decades. The proportion of the current ages of Vijaya and Simran is : [ 0.1 Decates =1 Year; quadrice = 4 times]

0.1 decates ago, Vijaya was quadrice as old as her daughter Simran. 0.6 decades hence, Vijayas age will beat her daughters age by 0.9 decades. The proportion of the current ages of Vijaya and Simran is : [ 0.1 Decates =1 Year; quadrice = 4 times] Correct Answer 13:4

Let, Ages of Vijaya and Simran – 1 year ago was 4A and A years correspondingly. Then, [(4A + 1) + 6] – [(A + 1) + 6] = 93A = 9  => A = 3

 

Needed Ratio = (4A + 1) : (A + 1) = 13 : 4
