Question

5years ago age of nuri is thrice old as sonu. and 10 years later nuri will be twice old as sonu. how old are sonu and nuri?

Answer 1

let the 5 years ago age of Nuri be 3x and sonu's age be x then,


★ Ten years later age of sonu is
(x+5+10)=>(x+15)

★Ten years later age of nuri is (3x+5+10)=>3x+15


=>according to question:

3x+15=2(x+15)

3x+15=2x+30

x=15


we have:

age of sonu:

x+5=(15+5)=>20 years

age of nuri:

(3x+5)=45+5=>50 years

Answer 2

Let 5 years ago, Sonu's age = ( x ) years

And Nuri's age was = ( 3x ) years



10 years later, Sonu's age = ( x + 5 + 10 ) years = ( x + 15 ) years

And Nuri's age = ( 3x + 5 + 10 ) years = ( 3x + 15 ) years





According to the question :

(3x + 15) = 2(x + 15)

3x + 15 = 2x + 30

x = 15



Hence, present age of Sonu = ( x + 5 ) = 20 years

And Present age of Nuri = ( 3x + 5) = 50 years
