Solution

Statement I

 Let the present age of Alok be ‘x’ years.

Ram’s age = Alok’s age  = ‘x’ years.

Rahul’s age = (x+2) years

ATQ,

Rahul's age Ajit's age = 9/8

(x+2)/Ajit = 9/8

Ajit’s age = 8/9 x (x+2)

Statement II: 

x+x = (x+2) + 8/9 x (x+2)-1

2x =  (x+2) x 17/9 -1 

2x-(17/9)x = 34/9 -1

x/9 = 25/9

x=25

ALok’s age = Ram’s age = 25 years

Rahul’s age = 25+2 = 27 years 

Ajit’s age = (8/9) x 27 = 24 years.
