Answer:
12
Explanation:
Suppose the four different strains are P, Q, R, S. Thus, the first infection can be from any of the four strains and it occurs in 4 ways.
Since an individual cannot be infected again with the strain from which he/she is been previously infected;
Then, at the second time;
The possible number of strain to be infected with = 4-1 = 3 ways
Thus; the number of possible different levels of severity can be viewed by forming two lettered word P, Q, R, and S without repetition which is:
= 4 × 3
= 12
Answer:
Option B, 
hectoliters
Explanation:
As we know that in one hectoliter there are ten decaliters
hectoliter 
decaliters
or
decaliters 
hectoliter
For converting any small unit into a large unit it is to be divided by number of units in large unit.
Thus,
decaliters in terms of hectoliter is equal to
Hence, option B is correct
