The respective ratio between the present age Aarti and Savita is 5 : x. Aartl is 9 years younger than Jahnavi. Jahnavi's age after 9 years will be 33 years. The difference between Savita's and Aarti's age is same as the present age of Jahnavi. What will come in place of x?

  • 4]

    13

Solution

Jahnavi's present age= 33 - 9 = 24 years

Aarti's present age= 24 - 9 = 15 years

 Aarti : Savita= 5 : x = 15 : 3x

Therefore, Savita present age= 3x years

Therefore, 3x - 15 = 24

=> 3x = 24 + 15 = 39

=> x = 393393 = 13
