Answer 2

Answer:

The number best completing analogy is $5$.

Step-by-step explanation:

We are given $8:4 :: 10:?$.

Same logic which is used in first pair will be used in the other one.

One pair $8:4$.

We can see that the logic is that second number is half of the first.

Hence,

In second pair

$10:?$

Half of first number is $10/2=5$

Hence, $10:5$

Analogy is completed as $8:4 :: 10:5$
