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!
To do:
We have to solve the given riddle.
Solution:
Let the required number be $x$
$7\times x + 50 = 300 - 40$
$7x+50= 260$
$7x = 260 - 50$
$7x= 210$
$x = \frac{210}{7}$
$x= 30$
So, the required number is 30.
