Select the option that is related to the fourth number in the same way as the first number is related to the second number and fifth number is related to sixth number.
11 : 1000 :: ? : 1728 :: 9 : 512
Answer & explanation
Correct answer: option 4
Pattern followed is : X : (X-1)3
11 : 1000 ⇒ 11 : (11-1)3 ⇒ 11 : 103 ⇒ 11 : 1000
same as
9 : 512 ⇒ 9 : (9 - 1)3 ⇒ 9 : 83 ⇒ 9 : 512
Similarly ,
x : 1728 ⇒ x : 123 ⇒ x : (13 - 1)3 ⇒ x = 13
13 , is correct answer .
