11 : 1000 :: ? : 1728 :: 9 : 512
Option 1: 15
Option 2: 7
Option 3: 5
Option 4: 13
Correct Answer: 13
Solution :
Given:
11 : 1000 :: ? : 1728 :: 9 : 512
Like, 11 : 1000→(11 – 1)
3
= (10)
3
= 1000
9 : 512→(9 – 1)
3
= (8)
3
= 512
Let's check the options –
First Option:
15→(15 – 1)
3
= (14)
3
= 2744 ≠ 1728
Second Option:
7→(7 – 1)
3
= (6)
3
= 216 ≠ 1728
Third Option:
5→(5 – 1)
3
= (4)
3
= 64 ≠ 1728
Fourth Option:
13→(13 – 1)
3
= (12)
3
= 1728
So, 13 is related to 1728. Hence, the fourth option is correct.
