दिलेले समीकरण: 7 * 9 + 3 ÷ 7 − 3 = 25.
आता, पर्यायांमध्ये दिलेल्या चिन्हांची अदलाबदल करा.
1) ÷ आणि *
दिलेले समीकरण: 7 * 9 + 3 ÷ 7 − 3 = 25
'÷ आणि *' अदलाबदल केल्यानंतर, आपल्याला मिळते:
डाव्या हाताची बाजू = 7 ÷ 9 + 3 * 7 − 3
= 0.78 + 3 * 7 - 3
= 0.78 + 21 - 3
= 21.78 - 3
= 18.78 ≠ उजव्या हाताची बाजू
2) ÷ आणि +
दिलेले समीकरण: 7 * 9 + 3 ÷ 7 − 3 = 25
‘÷ आणि +’ अदलाबदल केल्यानंतर, आपल्याला मिळते:
डाव्या हाताची बाजू = 7 * 9 ÷ 3 + 7 − 3
= 7 * 3 + 7 − 3
= 21 + 7 - 3
= 28 - 3
= 25 = उजव्या हाताची बाजू
3) + आणि *
दिलेले समीकरण: 7 * 9 + 3 ÷ 7 − 3 = 25
'+ आणि *' अदलाबदल केल्यानंतर, आपल्याला मिळते:
डाव्या हाताची बाजू = 7 + 9 * 3 ÷ 7 − 3 = 25
= 7 + 3.857 - 3
= 10.857 - 3
= 7.857 ≠ उजव्या हाताची बाजू
4) + आणि −
दिलेले समीकरण: 7 * 9 + 3 ÷ 7 − 3 = 25
'+ आणि -' अदलाबदल केल्यानंतर, आपल्याला मिळते:
डाव्या हाताची बाजू= 7 * 9 - 3 ÷ 7 + 3
= 7 * 9 - 0.42 + 3
= 63 - 0.42 + 3
= 66 - 0.42
= 65.58 ≠ उजव्या हाताची बाजू
म्हणून, योग्य उत्तर "पर्याय 2" आहे.
