Select the odd group of numbers. (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)
Answer & explanation
Correct answer: option 2
THE LOGIC FOLLOWED HERE IS :
IST NUMBER2 + 5 = IIND NUMBER
AS
18 - 329
182 + 5 = 324 + 5 = 329
16 - 263
162 + 5 = 256 + 5 = 261 ≠ 263 (ODD)
14 - 201
142 + 5 = 196 + 5 = 201
12 - 149
122 + 5 = 144 + 5 = 149
