Question

In each of the following question, select the related number from the given alternatives.
$8$ $:$ $64$ $:$ $:$ $27$ $:$ $?$

• A. $64$
• B. $81$
• C. $212$
• D. $125$

Answer 1

Answer: (D)

$125$

Looking at the first set $8:64$

$8$ is the cube of $2$ and $64$ is the cube of $4$ . Difference between $4$ and $2$ is $2$.

By the same relation $27$ is the cube of $3$ and required number should be cube of $3+2=5$ i.e. $125$

So correct answer is option $D$
