Question

Arjun is twice as old as Sumans 5 years ago his age was three times Sumans age then Sumans present age ls

Answer 1

let sumans age be = x
then arjun age = 2x
5 years ago the age of suman = x-5
5 years ago the age of arjun = 3( x-5)
according to the sum :-
        3(x-5) = x-5
        3x-15 = x-5
         3x -x = -5+15
          2x  = 10
            x = 10/2 = 5
sumans age is 3( 5-5)
                        15-15 = 0

Answer 2

Let suman be x years old. then Arjun be 2x years old.
5 years ago.
2× -5 = 3x.
2x - 3x = 5
-1× = 5
× = -5
Suman's present age 5 yrs old.
Arjun = 2 ×5 = 10 yrs old.
