Correct Answer: 117


Solution : Given:
17 : –153 :: –13 : ? :: –21 : 189

Multiply the first number by –9, to obtain the second number in each number pair –
Like, ​​​​​​​ 17 : –153→17 × (–9) = –153
And, –21 : 189→–21 × (–9) = 189
Similarly, follow the same pattern for –13 : ?→
–13 × (–9) = 117

So, 117 is the required missing number. Hence, the second option is correct.
