81 + 3 ÷ 9 * 5 − 12 = 60
गणना:
पर्याय पद्धतीनुसार:
पर्याय 1: अदलाबदल ÷ आणि +
⇒ 81 ÷ 3 + 9 * 5 − 12 = 60
⇒ 27 + 45 -12 = 60
⇒ 60 = 60
हे समीकरण योग्य आहे.
पर्याय 2: अदलाबदल + आणि *
⇒ 81 * 3 ÷ 9 + 5 − 12 = 60
⇒ 27 +5 - 12 = 60
⇒ 20 ≠ 60
हे समीकरण योग्य नाही.
पर्याय 3: अदलाबदल ÷ आणि –
⇒ 81 + 3 - 9 * 5 ÷ 12 = 60
⇒ 81 + 3 - 3.75 = 60
⇒ 80.25 ≠ 60
हे समीकरण योग्य नाही.
पर्याय 4: अदलाबदल + आणि –
⇒ 81 - 3 ÷ 9 * 5 + 12 = 60
⇒ 81 - 1.66 + 12 = 60
⇒ 91.34 ≠ 60
हे समीकरण योग्य नाही.
∴ अदलाबदल (÷ आणि +) दिलेले समीकरण योग्य करेल.
