दिलेल्या डेटावरून, आम्हाला मिळते
⇒ 2 (x - y) = x + y
केस १
जेव्हा, x = 15
⇒ 2 (15 - y) = 15 + y
⇒ 30 - 2y = 15 + y
⇒ 15 = 3y
⇒ y = 5
केस 2
जेव्हा, y = 15
⇒ 2 (x - y) = x + y
⇒ 2 (x - 15) = x + 15
⇒ 2x - 30 = x + 15
⇒ x = 45
∴ दुसरी संख्या 5 किंवा 45 आहे
गोंधळाचे मुद्दे प्रश्नात दुसरी संख्या शोधण्यास सांगितले जाते आणि इतर संख्या 5 किंवा 45 असू शकतात.
पहिल्या क्रमांकाबद्दल विचारले जात नाही म्हणून 15 आणि 45 हे बरोबर उत्तर नाही.
