गणना :
पर्याय पद्धतीनुसार:
पर्याय 1 : 18, 11 दोघांची अदलाबदल करुन
⇒
⇒11 + 72 + 9 x 4 + 3 - 18 = 112
⇒ 11 + 72 + 36 +3 -18 = 112
⇒ 104 ≠ 112
हे योग्य समीकरण नाही.
पर्याय 2 : 12, 4 दोघांची अदलाबदल करुन
⇒
⇒ 18 + 24 + 9 x 12 + 3 -11 = 112
⇒ 142 ≠ 112
हे योग्य समीकरण नाही.
पर्याय 3: 6, 4 दोघांची अदलाबदल करुन
⇒
⇒ 18 + 48 + 9 x 6 + 3 -11 = 112
⇒ 18 + 48 + 54 + 3 -11 = 112
⇒ 112 = 112
हे योग्य समीकरण आहे.
पर्याय 4: 18, 12 दोघांची अदलाबदल करुन
⇒
⇒ 12 + 108 + 9 x 4 +3 -11 =112
⇒ 148 ≠ 112
हे योग्य समीकरण नाही.
म्हणून, योग्य उत्तर 'पर्याय 3' हे आहे.
