Correct Answer: 42 – 29
Solution :
Let's check the options –
First option:
73 – 61
→
73 – 61 = 12
Second option:
57 – 69
→
69 – 57 = 12
Third option:
47 – 59
→
59 – 47 = 12
Fourth option:
42 – 29
→
42 – 29 = 13

So, the fourth option differs from the other three options as the difference between the numbers is 13 instead of 12. Hence, the fourth option is correct.
