Four number-pairs have been given, out of which three
are alike in some manner and one is different. Select the number-pair that is different.Solution
461 : 20 → 20² + 3 x 20 + 1 = 400 + 61 = 461 182 : 12→ 12² + 3 x 12 + 1 = 144 + 37 = 181 239 : 14→ 14² + 3 x 14 + 1 = 196 + 43 = 239 305 : 16→ 16² + 3 x 16 + 1 = 256 + 49 = 305
