Correct Answer: 216


Solution : Given:
10 : 512 :: 12 : 1000 :: 8 : ?

Subtract 2 from the first number, and then cube the resultant, to obtain the second number in each number pair –
Like, 10 : 512→(10 – 2) 3 = 8 3 = 512
And, 12 : 1000→(12 – 2) 3 = 10 3 ​ = 1000
Similarly, follow the same pattern for 8 : ?→
⇒ (8 – 2) 3 = 6 3 ​ = 216

So, 216 is the required missing number. Hence, the second option is correct.
