Question

Nitin is as old as 3 times Rohit is after 3 years , he will be twice as old as Rohit , find their present age ?

Plz plz answer it fast and tommorow is my exam plz answer it as fast as you can

Answer 1

Let the present age of Rohit be x years

Nitin is 3 times Rohit's age

∴ Nitin's age = 3x

After 3 years,

Age of Rohit = x + 3

Age of Nitin = 3x + 3

According to the given condition.

2(x + 3) = 3x + 3

☛ 2x + 6 = 3x + 3

☛ 6 - 3 = 3x - 2x

∴ 3 = x

∴ Present age of Rohit ☛ x years

☛ $\large{\boxed{\boxed{\rm{3\:years}}}}$

∴ Present age of Nitin ☛ 3x years

☛ 3 × 3

☛ $\large{\boxed{\boxed{\rm{9\:years}}}}$

Answer 2

let the age of Rohit be x

age of nitin 3x

after 3 years,

Nithin age 3x + 3= 2(x+3)

3x+3=2x+6

x=3

age of nitin 3x=3×3=9
