Ruchir was aked his age by his friend. Ruchir said ''The number you get when you subtract 25 times my age from twice the square of my age will be thrice your age. If the friend's age is 14, then the age of Ruchir is
(a) 20
(b) 22
(c) 28
(d) 14
Let the age of Ruchir be x years.
Age of Ruchir's friend = 14 years
Given, 2 × (Age of Ruchir)2 – 25 × Age of Ruchir = 3 × Age of Ruchir's friend
Thus, age of Ruchir is 14 years.
