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.
12 : 216 :: ? : 729 :: 24 : 1728
Answer & explanation
Correct answer: option 3
12 : 216 :: ? : 729 :: 24 : 1728
The logic followed here is
(X ÷ 2 )3
12 : 216
(12 ÷ 2 )3 = 63 = 216
and
24 : 1728
(24 ÷ 2 )3 = 123 = 1728
therefore
? : 729
(18 ÷ 2 )3 = 93 = 729
18 is the number which is half of 9 and 93 = 729
