यहाँ अनुसरण किया गया तर्क इस प्रकार है:

दी गई संख्या: 9345712

विषम अंकों में से - 1 को घटाया जाता है

और, सम अंक में + 2 जोड़ा जाता है

संख्याओं को व्यवस्थित करने के बाद:

9345712 ⇒ 8264604

अब, शृंखला को पुनर्व्यवस्थित करने के बाद सबसे बड़ा अंक: 8

और, शृंखला को पुनर्व्यवस्थित करने के बाद सबसे छोटा अंक: 0

इसलिए, सबसे बड़े और सबसे छोटे अंक के बीच का अंतर है: 8 - 0 = 8

अतः, सही उत्तर "विकल्प 2" है।
