Select the set in which the numbers are related in the same way as are the numbers of the following 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 to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(57, 41, 32)
(65, 49, 40)​

Given: 

(57, 41, 32)
(65, 49, 40)

Logic: 1st number - 16 = 2nd number and 2nd number - 9 = 3rd number

For, (57, 41, 32)

57 - 16 = 41, 41 - 9 = 32

For, (65, 49, 40)

65 - 16 = 49, 49 - 9 = 40

Now, we check each options.

Option (a): (51, 35, 16) (Not Follow)

51 - 16 = 35, 35 - 9 $$\neq$$​ 16

Option (b): (72, 56, 47) (Follow)​

72 - 16 = 56, 56 - 9 = 47

Option (c): (89, 83, 74) (Not Follow)​

89 - 16 $$\neq$$​ 83, 83 - 9 = 74

Option (d): (96, 80, 61) (Not Follow)​

96 - 16 = 80, 80 - 9 $$\neq$$​ 61

Thus, correct option is (b).
