Question

Donating blood is a humanitarian act as per a server 16000 blood donors are registered with red cross in Delhi and this number of Donor increases at the rate of 5% every six month how many hours will it be at the end of 3 by 2 years

Answer 1

Answer:1 whole 1 by 2 years is assumed to be 1.5 years i.e. 6 months * 3

After first 6 months donors will be: 16000 (1 +  r/100) = 16000 (1 + 5/100) = 16800

After next 6 months donors will be: 16800 (1 +  r/100) = 16800 (1 + 5/100) = 17640

After next 6 months donors will be: 17640 (1 +  r/100) = 17640 (1 + 5/100) = 18522

So, number of donors after 1.5 year will be 18522
