Let’s use the question stem to create a table :
| Male | Female | Total | |
| Teachers | x | 3x | 4x |
| Non Academics | 2x | ||
| 6x |
Statement 1:
Exactly 14 of the teachers at the school are males who are non-academic staff.
so, the value below x becomes 14 ( non academic male ) , female = 2x -14.
since, we cannot find x, insufficient.
Statement 2:
There are 32 more female teachers than male teachers at the school.
3x - x = 2x = 32
Thus, x = 16.
Hence, 6x = 6*16 = 96. Hence, Sufficient.

| Male | Female | Total | |
| Non-Academic | x/2 | ||
| academic | x/2 | ||
| Total | x/4 | 3x/4 | X |
We have this info:
option 1:
14 teachers are male and non academic
This does not help to figure out the total number of teachers. (not sufficient)
Option 2
3x/4-x/4=32 =>2x/4=32=> x=64. Sufficient . Hence it should be option B
