Below are given two sets of numbers. In each set of numbers, a certain mathematical ope ration on the first number results in the second number. Similarly, certain mathe matical operation on the second number results in the third number and so on. Which of the given operations follows the same set of operations as in question? (NOTE - A two/three-digit number cannot be broken into individual digits for operations e.g. if 37 is followed by 10 , the operation cannot be 3+7 as a two-digit number cannot be broken into individual digits)
2-8-15-5
5-125-132-44

Information Given:
2 → 8 → 15 → 5
5 → 125 → 132 → 44

Logic:
First → Second: Cube of the number

Second → Third: + 7

Third → Fourth: ÷ 3

2 → 8 → 15 → 5
2³ = 8 
8 + 7 = 15 
15 ÷ 3 = 5 

​5 → 125 → 132 → 44
5³ = 125 
125 + 7 = 132 
132 ÷ 3 = 44 

A) 8 → 512 → 519 → 173
8³ = 512 
512 + 7 = 519 
519 ÷ 3 = 173 

1³ = 1 
1 + 7 = 8 ≠ 9 ✘

7³ = 343 
343 + 7 = 350 ≠ 336 ✘

12³ = 1728 
1728 + 7 = 1735 
1735 ÷ 3 ≠ 347 ✘

Final Answer:
8-512-519-173

Final Correct Option:
(a)
