Mathematics Question on Compound Interest
In a laboratory, the count of bacteria in a certain experiment was increasing at the rate of 2.5 % per hour. Find the bacteria at the end of 2 hours if the count was initially 5,06,000.
Answer
The initial count of bacteria is given as 5,06,000.
Bacteria at the end of 2 hours = 506000(1+1002.5)2
= 506000(1+401)2=5060000×4041×4041
531616.25=5,31,616(approx)
Thus, the count of bacteria at the end of 2 hours will be 5,31,616(approx.).
