1.	Four number-pairs have been given below, out of which three are alike in some manner and one is different. Select the odd one from the option.1. 156 : 122. 210 : 143. 240 : 154. 276 : 16
Answer» Correct Answer - Option 4 : 276 : 16 The logic follows here is : (I). 156 : 12 12² + 12 = 144 + 12 = 156 (II). 210 : 14 14² + 14 = 196 + 14 = 210 (III). 240 : 15 15² + 15 = 225 + 15 = 240 (IV). 276 : 16 16² + 16 = 256 + 16 = 272 ≠ 276 Thus, 276 : 16 is the odd one. Hence, the correct answer is "276 : 16".

Answer» Correct Answer - Option 4 : 276 : 16

The logic follows here is :

(I). 156 : 12

12² + 12 = 144 + 12 = 156

(II). 210 : 14

14² + 14 = 196 + 14 = 210

(III). 240 : 15

15² + 15 = 225 + 15 = 240

(IV). 276 : 16

16² + 16 = 256 + 16 = 272 ≠ 276

Thus, 276 : 16 is the odd one.

Hence, the correct answer is "276 : 16".
