The rate at which microbe multiply is proportional to the instantaneous number present . If the original number doubles in 2 hours, then they will triple in-

It given that the rate at which some bacteria multiply is proportional to the instantaneous number presents. If the original number of bacteria doubles in two hours, in how many hours will it be five times?

It given that the rate at which some bacteria multiply is proportional to the instantaneous number presents.If the original number of bacteria doubles in two hours,in how many hours will it be five xx?

Bacteria multiply at the rate proportional to the number of bacteria present.If the original number N doubles in 3 hours,show that the number will be 4N in 6 hours.

In a certain culture of bacteria, the rate of increase is proportional to the number present. If it is found that the number doubles in 4 hours, find the number of times the bacteria are increased in 12 hours.

Bacteria increases at the rate proportional to the number of bacteria present. If the original number N doubles in 3 hours, find in how many hours the number of bacteria will by 4N ?
