Two sets of numbers are given below. In each set of numbers, the second number is obtained by performing certain mathematical operations on the first number. Similarly, the third number is obtained by performing the same operations on the second number, and so on for the subsequent numbers. Which of the given options follows the same pattern as the given sets?
(Note: The numbers should not be split into their digits. Operations must be performed on the complete numbers. For example, for 13, operations like adding/subtracting/multiplying etc. should be performed on 13, and not by splitting 13 into 1 and 3.)
33 - 36 - 31 - 124
38 - 41 - 36 - 144
- A.
32 - 36 - 31 - 155
- B.
49 - 52 - 47 - 188
- C.
31 - 33 - 28 - 112
- D.
41 - 44 - 37 - 185

Show answer & explanation
Correct answer: B
Step 1: Decode the mathematical pattern in the given sets.
Set 1: 33 (+3) = 36; 36 (-5) = 31; 31 (×4) = 124.
Set 2: 38 (+3) = 41; 41 (-5) = 36; 36 (×4) = 144.
The established logic is: +3, -5, ×4.
Step 2: Test Option B with the same logic.
49 (+3) = 52
52 (-5) = 47
47 (×4) = 188.
This matches the set perfectly.
Final Answer: Option B
