Correct Answer: 54 : 17
Solution :
Let's check the options –
First option:
42 : 2; 42 ÷ 2 = 21; 42 is divisible by 2.
Second option:
81 : 9; 81 ÷ 9 = 9; 81 is divisible by 9.
Third option:
24 : 6; 24 ÷ 6 = 4; 24 is divisible by 6.
Fourth option:
54 : 17; 54 is not divisible by 17.
So, the fourth option differs from the other three options because the first number is not the multiple of the second number. Hence, the fourth option is correct.
