Correct Answer: 15 – 41
Solution :
Let’s check the options –
First option:
34 – 43
; Reversing the digits of 34 leads to the number 43.
Second option:
57 – 75
; Reversing the digits of 57 leads to the number 75.
Third option:
12 – 21
; Reversing the digits of 12 leads to 21
Fourth option:
15 – 41
; Reversing the digits of 15 leads to 51 ≠ 41
So, the fourth option is different from the other three options because on reversing the first number, the number formed is 51 instead of 41. Hence, the fourth option is correct.
