Question

24,000 blood donors were registered with a charitable hospital.The number of donors increased at the rate of 5 percent every six month.Find the total number of blood donors​

Answer 1

Answer:

1,20,000 is the total number of blood donors

Step-by-step explanation:

24,000 × 5 = 1,20,000

So the number of donors = 1,20,000

Answer 2

Answer:

11/2 year

Step-by-step explanation:

P(1+R/100) ^n

Substituting values, we get,

27783 = 24000 (1+ 5/100 ) ^ n

27783 24000 ( 1+ 1/20) ^n

Bringing 24000 to the denominator of LHS

27783/24000 = (21/20) ^n

Dividing LHS Numerator and Denominator by

common divisor 3, we get

9261/8000 = (21/20) ^n

Finding the LHS square root, we get

(21/20) ^3 = (21/20) ^n

Comparing LHS and RHS, we see n = 3

Therefore, Time period 3* 6 months = 18 months

= 1 1/2 year.
