Vivek is 3 times as old as Tarun. Sourabh was twice as old as Vivek 4 years ago. In 4 years, Vivek will be of 31 years. What is the present age of Tarun and Sourabh, respectively?

It is a correct answer .Solution-Let Vivek's present age = x Similarly,Let Tarun's present age = y and Sourabh's present age = z
We know, x = 3*y z-4 = 2*(x-4) and (x+4) = 31 (Given In statement) x=27 Therefore, y = 9 z = 50 The age of tarun is 9 years and of sourabh is 50 years.
