Rajan got married 8 years ago. His present age is 65times his age at the time of his marriage. Rajan's sister was 10 years younger to him at the time of his marriage. The age of Rajan's sister is:
38 years
Let Rajan's present age be x years. Then, his age at the time of marriage = (x - 8) years.
x = 65(x−8)
⇒5x=6x−48
⇒x=48 years
Rajan's sister's age at the time of his marriage = (x - 8) - 10 = (x - 18) = 30 years
∴ Rajan's sister's present age = (30 + 8) years = 38 years
