Question 5
A four-digit positive integer is called “good” if it consists of two pairs of same digits in some order but not all four digits are the same. For example, the numbers $2211$, $2424$ and $7007$ are good, while $5555$ and $3111$ are not. Find the total number of “good” four-digit positive integers which are divisible by $7$ or $101$, but not divisible by both.
