0.1 decates ago, Vijaya was quadrice as old as her daughter Simran. 0.6 decades hence, Vijaya’s age will beat her daughter’s age by 0.9 decades. The proportion of the current ages of Vijaya and Simran is : [ 0.1 Decates =1 Year; quadrice = 4 times]
Answer: D
Let, Ages of Vijaya and Simran – 1 year ago was \(4A\) and \(A\) years respectively.
Then, \([(4A + 1) + 6] - [(A + 1) + 6] = 9\)
\(\Rightarrow3A = 9 \)
\(\Rightarrow A=3\)
Needed Ratio = \((4A + 1) : (A + 1) = 13 : 4\)
