Two sets of numbers are given below. In each set of numbers, certain mathematical operation(s) on the first number results in the second number. Similarly, certain mathematical operation(s) on the second number results in the third number and so on. Which of the given options follows the same set of operations as in the given sets?
(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting/multiplying to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
6 – 24 – 124 – 139; 8 – 32 – 132 – 147

Information Given:
Set1: 6 → 24 → 124 → 139
Set2: 8 → 32 → 132 → 147

Logic:
1st → 2nd: ×4
2nd → 3rd: +100
3rd → 4th: +15

Step-by-step:
6 × 4 = 24 → 24 + 100 = 124 → 124 + 15 = 139
8 × 4 = 32 → 32 + 100 = 132 → 132 + 15 = 147

Check options:
A: 11×4 = 44  → 44+100 = 144  → 144+15 = 159 ✔
B: 18×4 ≠ 132 ✘
C: 14×4 = 56  but 56+100 ≠ 62 ✘
D: 12×4 = 48  but 48+100 ≠ 52 ✘

Short Trick:
Observe pattern: ×4 → +100 → +15.

Final Answer:
11 – 44 – 144 – 159

Final Correct Option:
A
