Download Solution PDFदिलेली दोन चिन्हे आणि संख्यांची अदलाबदल केल्यास खालीलपैकी कोणते समीकरण बरोबर नसेल?
+ आणि ×, 5 आणि 4
I. 4 + 8 × 5 – 7 ÷ 1 = 37
II. 5 × 3 – 4 + 6 ÷ 2 = –8
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFI. 4 + 8 × 5 – 7 ÷ 1 = 37
दिलेल्या समीकरणातील चिन्हे + आणि ×, आणि संख्या 5 आणि 4 यांची अदलाबदल केल्यानंतर, आपल्याकडे आहे
5 × 8 + 4 – 7 ÷ 1 = 37
BODMAS नियम लागू केल्यावर आपल्याला मिळेल
5 × 8 + 4 – 7 = 37
⇒ 40 + 4 – 7 = 37
⇒ 44 - 7 = 37
⇒ 37 = 37
दिलेले समीकरण बरोबर आहे.
II. 5 × 3 – 4 + 6 ÷ 2 = –8
दिलेल्या समीकरणातील चिन्हे + आणि × आणि संख्या 5 आणि 4 यांची अदलाबदल केल्यानंतर, आपल्याकडे आहे
4 + 3 – 5 × 6 ÷ 2 = –8
BODMAS नियम लागू केल्यावर आपल्याला मिळेल
4 + 3 – 5 × 3 = –8
⇒ 4 + 3 – 15 = –8
⇒ 7 – 15 = –8
⇒ -8 = –8
दिलेले समीकरण बरोबर आहे.
म्हणून, "I किंवा II कोणतेही नाही" हे बरोबर उत्तर आहे.
