B8974886262777972
C7558597885888373
D7687867282687982

During August to October, which hospital has seen the maximum increase in the number of patients ?

  • A.B
  • B.C
  • C.A
  • D.D

Answer: C

The maximum increase was in hospital A.

The change in the number of patients each month is new admissions minus discharges. Adding August, September and October:

  • A: \((80 - 56) + (64 - 78) + (87 - 69) = 24 - 14 + 18 = 28\)
  • B: \(15 + 26 - 15 = 26\)
  • C: \(17 - 19 - 3 = -5\)
  • D: \(-11 + 14 + 14 = 17\)

Hospital A's net increase of 28 is the largest. B is close at 26, C actually fell, and D rose by 17. November is outside the period asked about.
