An English school and a Vernacular school are both under one superintendent. Suppose that the superintendentship, the four teachership of English and Vernacular school each, are vacant, if there be altogether 11 candidates for the appointments, 3 of whom apply exclusively for the superintendentship and 2 exclusively for the appointment in the English school, the number of ways in which the different appointment can be disposed of is :
(A) 268
(B) 1080
(C) 4320
(D) 6320
(E) 25920

We are filling in for 9 positions, one superintendent, 4 teacherships of each school. The superintendent has only 3 options. The Vernacular teachership is filled in by selecting any 4 from the rest of the candidates (11 - 3 - 2 = 6 people). Then we can note the rest of the 4 candidates will go towards the English school, so 6C4 options only for those 8 applicants.
So we should have 3*(6C4) groups but we are asking how the appointments can be arranged. Each school has 4 slots so that is an extra 4! to multiply for each school. Therefore the answer is \(3*(6C4)*4! * 4! = 3*(6C2) * 24 * 24 = 45 * 24 * 24 \approx 1000*24\) and the only close answer is E.

This question is poorly worded.
"Disposed of" is ambiguous at best.
There is nothing in the question that distinguishes the positions in the two schools beyond their overall missions of teaching English and Vernacular.
If the question had said "positions in each of four grade levels" then there would be a basis for the distinction.
So there is no basis for arranging the positions within each school at 4!*4!, reducing the answer to:
3*6!/4!2 = 45
