Math Problem Statement
for a three digit number abc, the number of three digit number that satisfy abc(number)=37(a+b+c) is?
Solution
Let be a three-digit number, which we can represent as . According to the problem, this number is equal to .
So we have the equation:
Expanding the right side, we get:
Now, rearrange the terms to bring all terms involving , , and to one side:
Dividing the entire equation by 9 for simplicity:
This equation needs to hold for integers , , and , where , , and are digits (0 to 9) and (since it’s a three-digit number). We can now analyze this equation to find valid combinations of , , and that satisfy it.
After finding valid values of , , and that meet the criteria, we can count the solutions.
