AgesThree years ago, Anurag’s age was thrice that of Bhragav. Two years hence Anurag’s age will be twice that of Bharagav. What is the present age of Anurag?1) 16 2) 18 3) 20 4) 22x – 3 = 3(y – 3) (1)(x + 2 ) = 2(y + 2) (2)x – 3y = – 6x – 2y = 2Hence – y = – 8 y = 8.X = 18.

AgesGoutam is four times as old as Girija. Four years hence, the age of Goutam will be thrice that of Girija. What is the present age of Goutam?1) 20 2) 24 3) 28 4) 32x = 4y (1)x + 4 = 3 ( y + 4) (2)Using (1) in (2)4y + 4 = 3y + 12Y = 8Hence x = 32
