In the given number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Select the number-pair in which the numbers are related in the same way as are the numbers of the given number-pairs. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
45, 88
26, 50 ​​

45, 88

26, 50

Logic: ​(First Number × 2) − 2 = Second Number

45 × 2 = 90 → 90 − 2 = 88

26 × 2 = 52 → 52 − 2 = 50

Let's check each options:

15 × 2 = 30 → 30 − 2 = 28 ≠ 32 

​Option B) 21 , 41

21 × 2 = 42 → 42 − 2 = 40 ≠ 41 

22 × 2 = 44 → 44 − 2 = 42 (Follow)

18 × 2 = 36 → 36 − 2 = 34 ≠ 36

Thus, the correct option is: (b) 21 , 41
