Question

Nitin is as old as three times Rohit is after 3 year he will be twice as old as Rohit find their present age

Answer 1

Let present age of Nitin be 'x'
Let present age of Rohit be 'y'
Therefore,
X = 3y
=> x - 3y=0............(1)

After 3 years,
Age of Nitin = x+3
Age of Rohit = y+3
Therefore,
X+3 =2(y+3)
x + 3=2y+6
x - 2y=3...........(2)

Subtract eq(1) & eq (2)

x - 3y=0
-(x- 2y=3)
________
-y = -3
________
Y=3 & x =9
