Correct answer is: None of these Explanation: Jahnavi’s present age = 33 - 9 = 24 years => Aarti’s present age = 24 - 9 = 15 years Now, Aarti : Savita = 5 : x = 15 : 3x => Savita’s present age = 3x years $\therefore 3x - 15 = 24$ $\implies 3x = 24 + 15 = 39$ $\implies x =\frac{39}{3}= 13$ Nithin ? answered undefined All Comments
