# Digit-related Problems

**Problem**

The digits of a three-digit number are in arithmetic progression. If you divide the number by the sum of its digits, the quotient is 26. If the digits are reversed, the resulting number is 198 more than the original number. Find the sum of all the digits.

A. 9 | C. 15 |

B. 12 | D. 18 |

## Digit-Related Problems

For any three digit number, let*h* = the hundreds digit*t* = the tens digit and*u* = the units digit

The number = 100*h* + 10*t* + *u*

The number with digits reversed = 100*u* + 10*t* + *h*

The sum of digits = *h* + *t* + *u*

The product of digits = *htu*
