Select the set in which the numbers are related in the same way as are the numbers of the following set.
(34, 15, 64)
(29, 17, 63)
(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/deleting/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.)

Correct option is C

Observing the given sets:
1. First Set: (34, 15, 64)
Add the first and second numbers:
34 + 2 (15) =  34 + 30 = 64
2. Second Set: (29, 17, 63)
Add the first and second numbers:
29 + 2(17) = 29 + 34 = 63
The pattern follows:
Third Number=First Number+ 2 (Second Number)
Apply the Pattern to the Given Options
Option A: (44, 32, 98)
• 44 + 2 (32)
• 44 + 64 = 108 (Not 98) Incorrect
Option B: (31, 23, 54)
• 31 + 2(23) 
• 31 + 46 = 77 (Not 54) Incorrect
Option C: (25, 14, 53)
• 25 + 2(14) 
• 25 + 28 = 53 (Correct) 
Option D: (24, 28, 76)
• 24 + 2(28) 
• 24 + 56 = 80 (Not 76) Incorrect
Final Answer:
The correct option is (C) (25, 14, 53).
