Question

Solve the following riddle.

I'm a number!
Tell my identity!
Take me seven times over!
And add a fifty!
To reach a triple century!
You still need forty! ​

Answer 1

The answer is :-30

Reason:-

It is told that the whole sum is less than a triple century by 40.

So 300-40=260

Now, 260-50=210

And, 210÷6=30
