Concept:Use positions in a queue and find the midpoint between two persons.
Explanation:Total persons in the queue are
48.
Harman is
14th from the front.
So Harman's position from front =
14.
Roshan is
17th from the end.
So Roshan's position from front =
48−17+1=32.
Persons between Harman and Roshan =
32−14−1=17.
Heena is in the middle of Harman and Roshan.
So there are
8 persons between Harman and Heena, and
8 persons between Heena and Roshan.
Thus, the required number of persons is
8.
