Correct Answer: 40


Solution : Given:
7 : 84 :: 5 : ? :: 9 : 144

Multiply the product of the first number and its preceding number by 2, to obtain the second number in each number pair –
Like, 7 : 84→(7 × 6) × 2 = 84
And, 9 : 144→(9 × 8) × 2 = 144
Similarly, follow the same pattern for 5 : ?→(5 × 4) × 2 = 40

So, 40 is related to 5. Hence, the second option is correct.
