Select the option that is related to the third term in the same way as the second term is related to the first term and the sixth term is related to the fifth term.
4 : 125 :: 9 : ? :: 11 : 1728

Given: 4 : 125 :: 9 : ? :: 11 : 1728

Logic: 1 is added in the first number and resultant is cubed to get second number.

As,

4 : 125

(4+1)³=5³=125

And

11 : 1728

(11+1)³=12³=1728

Similarly,

9 : ?

(9+1)³=10³=1000

Thus, correct option is (c).
