दिलेल्या दोन चिन्हे आणि संख्यांची अदलाबदल केल्यास खालील समीकरण बरोबर होईल.
दिलेले:- × आणि +, 6 आणि 4
पर्याय 1) 3 × 9 – 4 ÷ 2 + 6 = 8
चिन्हे आणि संख्यांची अदलाबदल केल्यानंतर आपल्याला मिळते:
⇒ 3 + 9 – 6 ÷ 2 × 4 = 8
⇒ 3 + 9 - 3 × 4 = 8
⇒ 3 + 9 - 12 = 8
⇒ 12 - 12 = 8
⇒ 0 ≠ 8
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
पर्याय 2) 8 × 6 + 4 ÷ 2 – 5 = –5
चिन्हे आणि संख्यांची अदलाबदल केल्यानंतर आपल्याला मिळते:
⇒ 8 + 4 × 6 ÷ 2 – 5 = –5
⇒ 8 + 4 × 3 - 5 = -5
⇒ 8 + 12 - 5 = -5
⇒ 20 - 5 = -5
⇒ 15 ≠ -5
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
पर्याय 3) 8 – 3 × 6 + 4 ÷ 1 = 18
चिन्हे आणि संख्यांची अदलाबदल केल्यानंतर आपल्याला मिळते:
⇒ 8 – 3 + 4 × 6 ÷ 1 = 18
⇒ 8 - 3 + 4 × 6 = 18
⇒ 8 - 3 + 24 = 18
⇒ 32 - 3 = 18
⇒ 29 ≠ 18
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
पर्याय 4) 7 × 6 – 4 + 9 ÷ 3 = –7
चिन्हे आणि संख्यांची अदलाबदल केल्यानंतर आपल्याला मिळते:
⇒ 7 + 4 – 6 × 9 ÷ 3 = –7
⇒ 7 + 4 - 6 × 3 = -7
⇒ 7 + 4 - 18 = -7
⇒ 11 - 18 = -7
⇒ -7 = -7
⇒ डाव्या हाताची बाजू = उजव्या हाताची बाजू
म्हणून, योग्य उत्तर "पर्याय 4" आहे.
