Correct Answer: 250


Solution : Given:
4 : 128 :: 5 : ? :: 7 : 686

Here, multiply the cube of the first number by 2 to get the second number –
Like in, 4 : 128→4 3 × 2 = 128
And in, 7 : 686 →7 3 × 2 = 686
Similarly by following the same method for 5 : ?→5 3 × 2 = 250

So, the required missing number is 250. Hence, the fourth option is correct.
