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.)

Correct Answer: 749 – 974
Solution :
Let's check each option –
First option:
317 – 713; 317 after interchanging the position of first and third digit→713
Second option:
342 – 243; 342 after interchanging the position of first and third digit→243
Third option:
749 – 974; 749 after interchanging the position of first and third digit→947 ≠ 974
Fourth option:
643 – 346; after interchanging the position of first and third digit→346
Therefore, the third option does not follow the same pattern as here the resultant is 947 instead of 974. Hence, the third option is correct.
