I guess the answer will be 30.
taking the number as x.
7x+50=300-40
7x=210
x=30

Step-by-step explanation:
Now it's time to solve a riddle. We have to identify the number for which several hints are given in the riddle.
I am a number,
Tell my identity!
Let the number be x
Take me seven times over
And add a fifty!
7 times x will be 7x
Adding 50 = 7x + 50
To reach a triple century
You still need forty!◻◻◼
↪Here, it is saying that to reach 300, we still need to add a 40. That means, the result of the previous step is 300 - 40 = 260. So, we can write it as:
⇛ 7x + 50 = 260
⇛ 7x + 50 = 260⇛ 7x = 210
⇛ 7x + 50 = 260⇛ 7x = 210⇛ x = 210 / 70
⇛ 7x + 50 = 260⇛ 7x = 210⇛ x = 210 / 70⇛ x = 30
Thus the number asked in the riddle is 30.
Thus the number asked in the riddle is 30.And we are done!
