Question

A computer can perform 30 identical tasks in 6 hour. At the rate, what is the minimum number of computer that should be assigned to complete 80 of the tasks with in 3 hours?

Answer 1

Answer:

of computers = 5+1 = 6. A computer can perform 30 identical tasks in six hours. At that rate, what is the minimum number of computers that should be assigned to complete 80 tasks within three hours? So, we need at least 5 and 1/3 machines, and since machines don't come in less than whole numbers, we need 6 machines.

Answer 2

Answer:

6 computer

Step-by-step explanation:

One computer can perform 30 task in 6 hr.

One Computer can perform 1 task in 6/30 hr = 1/5 hr

One computer can do 80 task in 80/5 hr = 16 hr

x computer needed to complete a job within 3 hr (with minimum number of computer)

$\frac{16}{x} \leqslant 3$

If x = 5 , 16/5 = 3.2 hr (more than 3 hr. so not a case)

if x = 6, 16/6 = 2.66 hr

Hence 6 number of computer needed to complete a job within 3 hr (with minimum number of computer)
