In the following question, a matrix of certain characters is given. These characters follow a certain trend, row-wise or column-wise. Find out this trend and choose the missing character accordingly.
| F | I | O |
| A | J | K |
| E | M | ? |
Option:

B. R
C. S

Tweet
Justification:
Putting A = 1, B = 2,..., Z = 26, we get the given matrix as
| 6 | 9 | 15 |
| 1 | 10 | 11 |
| 5 | 13 | ? |
Clearly, 1st column + 2nd column = 3rd column.
Now, 5 + 13 = 18.
So, the missing letter is the 18th letter of the alphabet, which is R.
