ఎంపిక పద్ధతి ద్వారా:
ఎంపిక 1 : మార్పిడి 18, 11
⇒
⇒11 + 72 + 9 x 4 + 3 - 18 = 112
⇒ 11 + 72 + 36 +3 -18 = 112
⇒ 104 ≠ 112
ఇది సరైన సమీకరణం కాదు.
ఎంపిక 2 : మార్పిడి 12, 4
⇒
⇒ 18 + 24 + 9 x 12 + 3 -11 = 112
⇒ 18 + 24 + 108 + 3 -11 = 112⇒ 142 ≠ 112
ఇది సరైన సమీకరణం కాదు.
ఎంపిక 3: మార్పిడి 6, 4
⇒
⇒ 18 + 48 + 9 x 6 + 3 -11 = 112
⇒ 18 + 48 + 54 + 3 -11 = 112
⇒ 112 = 112
ఇది సరైన సమీకరణం.
ఎంపిక 4: మార్పిడి 18, 12
⇒
⇒ 12 + 108 + 9 x 4 +3 -11 =112
⇒ 12 + 108 + 36 +3 -11 =112⇒ 148 ≠ 112
ఇది సరైన సమీకరణం.
ఎంపిక 4: మార్పిడి 18, 12
