Answer 2

Answer:

The given question: $729:841::1000: ?$.We should find the number analogy.

Answer: $729 : 841 :: 1000 : 900$

Step-by-step explanation:

• First take the left side ratio: $729 : 841$. Here we should find the combination between them.
• So that, $729$ can be written as, $729=(9)^3$ and $641$ can be written as, $841=(29)^2$.
• left side ratio: $729 : 841$ => $(9)^3:(29)^2$. This is similar to $n^3 : (n + 20)^2$and $n=9$.
• Now apply the same combination for right side ratio. That is

                   $1000 : ? = (10)^3:?$  => n = 10

                   $10^3 : (10 + 20)^2=(10)^3:(30)^2$

                  $(10)^3:(30)^2=1000:900$

• Final Answer: $729 : 841 :: 1000 : 900$
