In the following question, four options are given, out of which three are alike in a particular way while one is different. Choose the odd one.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 185
Option (1) 161 — \(161=7\times23\), a multiple of 23.
Option (2) 185 — \(185=5\times37\), not a multiple of 23, so 185 is the odd one out.
Option (3) 253 — \(253=11\times23\), a multiple of 23.
Option (4) 299 — \(299=13\times23\), a multiple of 23.
