Question : Directions: Select the odd group of numbers. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 –operations on 13 such as adding/subtracting /multiplying etc. 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
Option 1: 18 - 329
Option 2: 16 – 263
Option 3: 14 – 201
Option 4: 12 – 149
Correct Answer: 16 – 263
Solution :
Let's check the options –
First option:
18 – 329; 18
2
+ 5 = 324 + 5 = 329
Second option:
16 – 263; 16
2
+ 5 = 256 + 5= 261 ≠ 263
Third option:
14 – 201; 14
2
+ 5 = 196 + 5 = 201
Fourth option:
12 – 149; 12
2
+ 5 = 144 + 5 = 149
So, the second option is different from the other three options as here the resultant is 261 instead of 263. Hence, the second option is correct.
