Answer 1

Answer:

4 lysosomes takes 2 hr 45 mins to digest 11 foreign invader

Explanation:

Given data:

No. of foreign invader is 11

Total number of lysosome is 4

If 1 hr is used for foreign invader then

From the data we have following

If 1 lysosomes take 1 hr to digest 1 foreign invader

Then

4 lysosomes take 1/4 hr to digest one foreign invaders

Therefore

4 lysosomes takes 11/4 hr to digest 11 foreign invader

11/4 mean  =  2 3/4 hr i.e 2 hr 45 mins.

Answer 2

The correct answer is 3 hours.

During the first hour, all of the 4 lysosomes will digest 4 foreign invaders.

During the second hour another 4 foreign invaders will be digested.

The remaining 3 foreign invaders will be digested by 3 lysosomes during the third hour.
