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 1
The logic followed here is :
14 - 208 = 142 + 12 = 208 (odd)
18 - 334 = 182 + 10 = 334
12 - 154 = 122 + 10 = 154
16 - 266 = 162 + 10 = 266
