Introduction:
The riddle states that there is a number which, when multiplied by seven and added to fifty, still falls forty units short of reaching a triple century (300). We need to find this mysterious number.
Let's break down the riddle step by step:
Step 1: Take me seven times over
To solve this part of the riddle, we need to find a number that, when multiplied by seven, gives us a result.
Let's assume the number is "x":
7 * x = 7x
Step 2: And add fifty
After multiplying the number by seven, we need to add fifty to the result.
So, the equation becomes:
7x + 50
Step 3: To reach a triple century
The result of the equation in Step 2 still falls short of reaching a triple century (300) by forty units.
So, we can set up the equation:
7x + 50 + 40 = 300
Step 4: Solve the equation
Now, let's solve the equation from Step 3 to find the value of "x."
7x + 50 + 40 = 300
7x + 90 = 300
Subtract 90 from both sides of the equation:
7x = 210
Now, divide both sides of the equation by 7:
x = 30
Conclusion:
The mysterious number is 30. When multiplied by seven (7 * 30 = 210) and added to fifty (210 + 50 = 260), it still falls short of reaching a triple century by forty units.
