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.
