Solution

The number of malaria patients admitted in a hospital in 2001 = 4375
Rate of decrement of malaria patients = 8%
Time period = 2 yr [ 2003-2001= 2 yr]
Let the number of patients in 2003 be A.
By using formula, A=P(1R100)r
=4375(18100)2=4375×2325×2325=7×23×23=3703
Hence, the number of patients in 2003 was 3703.
