Gce Model Questions Vol1 2020 Computer Studies Question 43

The following Python function is intended to sum the differences between the larger and the smaller number for every unordered pair of distinct odd elements in a list that are coprime and whose product exceeds 200:\n\n```python\ndef mystery(lst):\n total = 0\n for i in range(len(lst)):\n for j in range(i+1, len(lst)):\n a, b = lst[i], lst[j]\n if a % 2 == 1 and b % 2 == 1: # both odd\n # check coprime\n def gcd(x, y):\n while y:\n x, y = y, x % y\n return x\n if gcd(a, b) == 1 and a*b > 200:\n total += max(a, b) - min(a, b)\n return total\n```\n\nWhat value does `mystery([9, 10, 14, 15, 22, 25])` return?
