Four pairs of numbers have been given, out of which three are alike in

1.	Four pairs of numbers have been given, out of which three are alike in some manner, while one is different. Choose out the odd one.1. 25 : 144 : 172. 121 : 49 : 193. 196 : 1 : 154. 9 : 361 : 22
Answer» Correct Answer - Option 2 : 121 : 49 : 19 The pattern followed here is: Square root of 1^stterm + Square root of 2^ndterm = Third term Option 1 → √25 + √144 = 5 + 12 = 17 Option 2 → √121 + √49 = 11 + 7 = 18 ≠ 19 Option 3 → √196 + √1 = 14 + 1 = 15 Option 4 → √9 + √361 = 3 + 19 = 22 Hence, '121 : 49 : 19' is the odd pair.

Answer» Correct Answer - Option 2 : 121 : 49 : 19

The pattern followed here is:

Square root of 1^stterm + Square root of 2^ndterm = Third term

Option 1 → √25 + √144 = 5 + 12 = 17

Option 2 → √121 + √49 = 11 + 7 = 18 ≠ 19

Option 3 → √196 + √1 = 14 + 1 = 15

Option 4 → √9 + √361 = 3 + 19 = 22

Hence, '121 : 49 : 19' is the odd pair.
