चला प्रत्येक पर्याय एक एक करून तपासूया:
दिलेल्याप्रमाणे: 7 आणि 4
पर्याय 1) 4 - 7 + 6 ÷ 2 × 3 = 12
संख्या बदलल्यानंतर आपल्याला मिळते;
⇒ 7 - 4 + 6 ÷ 2 × 3 = 12
⇒ 7 - 4 + 3 × 3 = 12
⇒ 7 - 4 + 9 = 12
⇒ 16 - 4 = 12
⇒ 12 = 12
⇒ डाव्या हाताची बाजू= उजव्या हाताची बाजू
पर्याय 2) 4 × 3 + 7 - 9 ÷ 3 = 20
संख्या बदलल्यानंतर आपल्याला मिळते;
⇒ 7 × 3 + 4 - 9 ÷ 3 = 20
⇒ 7 × 3 + 4 - 3 = 20
⇒ 21 + 4 - 3 = 20
⇒ 25 - 3 = 20
⇒ 22 ≠ 20
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
पर्याय 3) 7 + 4 × 2 - 6 ÷ 2 = 17
संख्या बदलल्यानंतर आपल्याला मिळते;
⇒ 4 + 7 × 2 - 6 ÷ 2 = 17
⇒ 4 + 7 × 2 - 3 = 17
⇒ 4 + 14 - 3 = 17
⇒ 18 - 3 = 17
⇒ 15 ≠ 17
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
पर्याय 4) 7 + 5 × 2 - 4 ÷ 1 = 9
संख्या बदलल्यानंतर आपल्याला मिळते;
⇒ 4 + 5 × 2 - 7 ÷ 1 = 9
⇒ 4 + 5 × 2 - 7 = 9
⇒ 4 + 10 - 7 = 9
⇒ 14 - 7 = 9
⇒ 7 ≠ 9
⇒ डाव्या हाताची बाजू ≠ उजव्या हाताची बाजू
म्हणून, योग्य उत्तर "पर्याय 1" आहे.
