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?

Expert Answer
Let current age of Sonu is y and Nuri's age is x.
Five years ago
Sonu's age = (y-5)
Nuri's age =(x-5) = 3(y-5)
x-3y+10 = 0 ………..(i)
Ten years later
Sonu's age = (y+10)
Nuri's age = x+10 = 2(y+10)
x-2y-10 = 0 …………..(ii)
(i) - (ii)
y = 20...Sonu
and x = 50...Nuri
