2. Five years ago, Nuri was thrice as old as Sonu. Ten years later, Nuri will be twice as old as Sonu. How old are Nuri and Sonu?

     Sol: Let the present age of Nuri  = x year
And present age of Sonu = y year
Five years ago
Age of Nuri = x – 5 years
Age of Sony = y – 5 years
Nuri was thrice as old as Sonu
X- 5  =  3(y – 5)
X – 5  =  35 – 15
X – 3y  =  -15  + 5
X – 3 y  = - 10                        ………..(1)
Ten years later,
Age of Nuri  = x + 10
Age of Sonu = y + 10
Nuri will be twice as old as Sonu.
X+ 10 = 2(y+10)
X + 10  = 2y + 20
X – 2y  = 10                           ………..(2)
X – 3 y  = - 10                        ………..(1)
Subtracting equation (1) from equation (2)  we get
Y  = 20
Plug this value in equation first we get
X  - 3* 20 = -10
X = 60 – 10
X  = 50
Hence age  of Nuri = 50 years and age of Sonu  = 20 years
