Correct Answer: 843 – 1181
Solution :
Let's check the options –
First option:

Second option:
843 – 1181→843 + 348 = 1191 ≠1181
Third option:
681 – 867→681 + 186 = 867
Fourth option:
507 – 1212→507 + 705 = 1212
So, the second option is different from the other three options. Hence, the second option is correct.
