The logic is:
Third Number =First Number + Second Number+1
Verification
12 : 47 : 60
12 + 47 + 1 = 60
4 : 16 : 20
4 + 16 + 1 = 21 ≠ 20
2 : 7 : 10
2 + 7 + 1 = 10
5 : 19 : 25
5 + 19 + 1 = 25
Final Answer
The triad that does NOT follow the logic is:
(b) 4 : 16 : 20

Find the odd one out.
Four number-sets have been given, out of which three are alike in some manner and one is different. Select the number-set that is different.(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.)
In three of the following four number pairs, the numbers are related in the same way and thus form a group. Which number pair DOES NOT belong to that group?
