Solve the following riddle:

I am a number,

Tell my identity!

Take me seven times over

And add a fifty!

To reach a triple century

You still need forty!

Answer :

Let us assume the number be x


So, according to the riddle given in the question:


(7x + 50) + 40 = 300


7x + 90 = 300


7x = 300 – 90


7x = 210


Now,


We have to divide both the sides by 7


=


7x = 210


x = 30


Hence,


The required number be 30
