In the following question, four number pairs are given. In each pair the number on left side of (–) is related to the number of the right side of (–) with some Logic/Rule/Relation. Three pairs are similar on basis of same Logic/Rule/Relation. Select the odd one out from the given alternatives. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
The pattern followed in the given options is:
Logic: (First term) 2 + 1 = Second term
Now we consider the given options:
Option 1) 12 – 145
⇒ (12) 2+ 1 = 145
⇒ 144 + 1= 145
⇒ 145 = 145
Option 2) 16 – 257
⇒ (16) 2 + 1 = 257
⇒ 256 + 1 = 257
⇒ 257 = 257
Option 3) 14 – 193
⇒ (14) 2 + 1 = 193
⇒ 196 + 1 = 193
⇒ 197 ≠ 193
Option 4) 10 –101
⇒ (10) 2 + 1 = 101
⇒ 100 + 1 = 101
⇒ 101 = 101
We can see that 14 - 193 does not follow the pattern so it is the odd one.
Hence, the correct answer is "Option 3".
