Four numbers have been given out of which three are alike in some manner while one is different...........

Logical Reasoning (CPO) Classification

Four numbers have been given out of which three are alike in some manner, while one is different. Choose the odd one.

171

169

195

- Let's analyze the options:

- 171: This number is \( 9 \times 19 \).

- 169: This is \( 13^2 \), a perfect square.

- 195: This number is \( 13 \times 15 \).

- 91: This number is \( 7 \times 13 \).

- Three numbers (169, 195, 91) are connected through the factor 13:

- 169: \( 13 \times 13 \)

- 195: \( 13 \times 15 \)

- 91: \( 13 \times 7 \)

- Only 171 does not have 13 as a factor.

- So, the odd one out is 171.
