Correct Answer: 840
Solution :
Total male faculties in all schools together = 8400
Male faculties in school A = 10% of 8400 = 840
The ratio of male faculties to female faculties in school A = 2 : 5
Female faculties in school A = $\frac{840}{2}×5$ = 2100
Male faculties in school B = 20% of 8400 = 1680
The ratio of male faculties to female faculties in school A = 4 : 3
Female faculties in school A = $\frac{1680}{4}×3$ = 1260
Difference in total female faculties in school A and school B
= 2100 – 1260
= 840
Hence, the correct answer is 840.
