Question

Question 74

In the year 2001, the number of malaria patients admitted in the hospitals of a state was 4375. Every year this number decreases by 8%. Find the number of patients in 2003.

Answer 1

The number of malaria patients admitted in a hospital in 2001 = 4375
Rate of decrement of malaria patients = 8%
Time period = 2 yr [$\because$ 2003-2001= 2 yr]
Let the number of patients in 2003 be A.
By using formula, $A=P{(1-\frac{R}{100})}^r$
$=4375{(1-\frac{8}{100})}^2=4375\times \frac{23}{25}\times \frac{23}{25}=7\times 23\times 23=3703$
Hence, the number of patients in 2003 was 3703.
