in a renowned city, the average birth rate is 9 people every two seconds and the death rate is 3 people every two seconds. estimate the size of the population net increase that occurs in one day.
multiply(multiply(subtract(9, 3), const_3600), const_12)
"every 2 seconds , 6 persons are added ( 9 - 3 ) . every second 3 persons are added . in a day 24 hrs = 24 * 60 minutes = 24 * 60 * 60 = 86400 seconds . 86400 * 3 = 259200 option e"
