Question

ramesh is twice as old as Suresh . two years hence Ramesh will be twice as old as Suresh. find Ramesh present age

Answer 1

Let age of ramesh be x year and of suresh be y years. So
x=2y and y+2=2(x+2)
putting these in together
y+2=2(2y+2)
y+2=4y+4
0=3y+2
y=-2/3

Hence this situation is not possible.
