Question : Directions: Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number.
8 : 514 :: 3 : 29 :: 7 : ?
Option 1: 325
Option 2: 355
Option 3: 335
Option 4: 345
Correct Answer: 345
Solution :
Given:
8 : 514 :: 3 : 29 :: 7 : ?
The second number is the sum of the cube of the first number and 2.
8 : 514→(8)
3
+ 2 = 512 + 2 = 514
3 : 29→(3)
3
+ 2 = 27 + 2 = 29
Similarly, 7 : ?→(7)
3
+ 2 = 343 + 2 = 345
So, 345 is related to 7. Hence, the fourth option is correct.
