Detailed Solution
Download Solution PDFआपण दिलेल्या समीकरणांमधील चिन्हे आणि संख्यांची अदलाबदल करतो आणि BODMAS नियम वापरून त्यांचे निराकरण करतो:
अदलाबदल करून: - आणि ÷, 8 आणि 2
I. 5 + 7 - 8 × 4 ÷ 2 = 9
⇒ 5 + 7 ÷ 2 × 4 - 8 = 9
⇒ 5 + 3.5 × 4 - 8 = 9
⇒ 5 + 14 - 8 = 9
⇒ 19 - 8 = 9
⇒ 11 ≠ 9
II. 3 + 8 × 4 - 2 ÷ 1 = 3
⇒ 3 + 2 × 4 ÷ 8 - 1 = 3
⇒ 3 + 2 × 0.5 - 1 = 3
⇒ 3 + 1 - 1 = 3
⇒ 4 - 1 = 3
⇒ 3 = 3
तर, फक्त । हे समीकरण योग्य नाही.
म्हणून, योग्य उत्तर "पर्याय 4" आहे.
