Question

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 1

let no. be x
$7x + 50 = 300 - 40$
$7x = 210$
$x = 30$

Answer 2

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!
