Question

donating blood is a humanitarian act as per a survey 16000 blood donors are registered with Red Cross in Delhi and this number of donors increase at the rate of 5% every 6 months how many donors would be there at the end of 1 whole 1 by 2 years

Answer 1

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
