<span>A diseases may be classified as either communicable or non-communicable. Communicable diseases are caused by pathogens who inhabit a host, man (I'm not saying man is the only host or man is necessarily the final host; there could be many host) who in turn passes the disease to another. Pathogens are viral, bacterial, parasitic and fungal. There are several stages before the pathogen metamorphoses into a full-blown disease. The stages in which several events happen builds up before the pathogen affects the final host is called a communicable disease chain. There are six stages ( Pathogen, reservoir, portal of ext, mode of transmission, portal of entry and susceptible host) in the communicable disease chain but the step a nurse shouod take is

Answer:
mg of powder 1 and
mg of powder 2
Explanation:
Let "X" denotes weight of powder 1 added to the new mixture and "Y" denotes weight of powder 2 added to the new mixture
Total weight of vitamin B1 in the mixture is equal to
mg
Total weight of vitamin B2 in the mixture is equal to
mg
Equation 1

Equation 2

Let us simplify the above two equations, we will get


Substituting value of X in equation 2 we get
