Question : Directions: Select the option 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.
3 : 8 :: 6 : ? :: 11 : 1000
Option 1: 216
Option 2: 512
Option 3: 125
Option 4: 729
Correct Answer: 125
Solution :
Given:
3 : 8 :: 6 : ? :: 11 : 1000
Subtract 1 from the first number, and then find the cube of the resultant number, to obtain the second number –
Like, 3 : 8→(3 – 1)
3
= 2
3
= 8
And, 11 : 1000→(11 – 1)
3
= 10
3
= 1000
Similarly, follow the same pattern for 6 : ?→
(6 – 1)
3
= 5
3
= 125
So, 125 is the required missing number. Hence, the third option is correct.
