Given Numbers:
A = 513
B = 135
C = 342
D = 124
1. Check the sum of the digits for each number:
- A = 513 : 5 + 1 + 3 = 9 (Divisible by 3)
- B = 135 : 1 + 3 + 5 = 9 (Divisible by 3)
- C = 342 : 3 + 4 + 2 = 9 (Divisible by 3)
- D = 124 : 1 + 2 + 4 = 7 (Not divisible by 3)
2. Observation:
- A , B , and C are divisible by 3 .
- D is not divisible by 3 .
The odd one out is D (124).

Three of the following four are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group?
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)

Three of the following number-pairs are alike in some manner and hence form a group.
Which number-pair does not belong to that group?
(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.)
