For this kind of question, you want to find the remainder after you divide the number in the boxes by the…”frequency”?
So for the question above, the arrangement pattern is
A – B – C – D – (repeat) – A – B – C – D
This has a frequency of 4, ie, the pattern repeats after every 4 numbers.
So you divide the numbers in the boxes by 4, and you will realise that under column A, the remainders are always 0, always 1 under B, always 2 under C, and always 3 under D.
A |
B |
C |
D |
|
|
6 / 4 -> 1R2 |
7/4 -> 1R3 |
8/4 -> 2R0 |
9/4 -> 2R1 |
10/4 -> 2R2 |
11/4 -> 2R3 |
12/4 -> 3R0 |
13/4 -> 3R1 |
14/4 -> 3R2 |
15/4 -> 3R3 |
Therefore, 134 / 4 -> 33 R 2 can be found in column C.
Likewise for your second question, the pattern is
A – B – C – D – D – C – B – A – (repeat) – A – B – C – D – D – C – B – A
This has a frequency of 8, so you find the remainder by dividing by 8.
A |
B |
C |
D |
2/8 -> 0R2 |
3/8 -> 0R3 |
4/8 -> 0R4 |
5/8 -> 0R5 |
9/8 -> 1R1 |
8/8 -> 1R0 |
7/8 -> 0R7 |
6/8 -> 0R6 |
10/8 -> 1R2 |
11/8 -> 1R3 |
12/8 -> 1R4 |
13/8 -> 1R5 |
The number 234 when divided by 8 has a remainder of 2, so it will be in column A.
