दिलेले समीकरण योग्य करण्यासाठी आपल्याला संख्यांची अदलाबदल करावी लागेल.
दिलेल्याप्रमाणे: 72 + (7 × 8) - (126 ÷ 14) - (4) 2 = 150
पर्याय 1) 72 आणि 126
संख्यांची अदलाबदल केल्यानंतर आपल्याला मिळते;
⇒ 126 + (7 × 8) - (72 ÷ 14) - (4)2 = 150
⇒ 126 + 56 - 5.14 - 16 = 150
⇒ 182 - 5.14 - 16 = 150
⇒ 160.86 ≠ 150
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
पर्याय 2) 7 आणि 4
संख्यांची अदलाबदल केल्यानंतर आपल्याला मिळते;
⇒ 72 + (4 × 8) - (126 ÷ 14) - (7) 2 = 150
⇒ 72 + 32 - 9 - 49 = 150
⇒ 104 - 9 - 49 = 150
⇒ 46 ≠ 150
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
पर्याय 3) 8 आणि 4
संख्यांची अदलाबदल केल्यानंतर आपल्याला मिळते;
⇒ 72 + (7 × 4) - (126 ÷ 14) - (8) 2 = 150
⇒ 72 + 28 - 9 - 64 = 150
⇒ 100 - 9 - 64 = 150
⇒ 27 ≠ 150
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
पर्याय 4) 14 आणि 7
संख्यांची अदलाबदल केल्यानंतर आपल्याला मिळते;
⇒ 72 + (14 × 8) - (126 ÷ 7) - (4)2 = 150
⇒ 72 + 112 - 18 - 16 = 150
⇒ 184 - 18 - 16 = 150
⇒ 150 = 150
⇒ डाव्या हाताची बाजू = उजव्या हाताची बाजू
म्हणून, योग्य उत्तर "पर्याय 4" आहे.
