The correct answer is
512

Analogy Pattern Identification

The question presents a number analogy: $100 : 1000 :: 64 : ?$. We need to find the relationship between the first pair of numbers (100 and 1000) and apply it to the second pair (64 and the missing number).

Finding the Mathematical Relationship

Observe the relationship between 100 and 1000:

  • $100 = 10^2$ (10 squared)
  • $1000 = 10^3$ (10 cubed)

The pattern appears to be $x^2 : x^3$. In the first pair, $x=10$.

Applying the Pattern

Now, let's apply this $x^2 : x^3$ pattern to the second pair, starting with 64:

  • $64 = 8^2$ (8 squared)

Here, $x=8$. Following the pattern, the missing number should be $x^3$.

Calculating the Missing Number

Calculate $8^3$:

$ 8^3 = 8 \times 8 \times 8 = 64 \times 8 = 512 $

Conclusion

The missing number is 512. This corresponds to Option C.
