Answer:

4 years

Explanation:

Let x be the age ( in years ) of each daughters,

∵ Mother is 30 years older than her daughters,

⇒ Age of the mother = x + 30

Now, after 2 years,

The age of each daughter = x + 2,

And, the age of the mother = x + 30 + 2 = ( x + 32 ) years,

According to the question,

3(x+2+x+2) = x + 32

3(2x+4) = x + 32

6x + 12 = x + 32

5x = 20

⇒ x = 4

Hence, each of the daughters is 4 years old.

Airida [17]

This question has no answer, as it explains the DEVELOPMENTS IN MEDICINE IN WESTERN SOCIETY OVER THE PAST THREE CENTURIES or safe to say this isn't exactly a question, rather it is a list of statements Sociologists are likely to develop in reference to the development of medicine in the western culture.

For instance, Sociologist is a scientist that studies the subject SOCIOLOGY which in turn is the study of society, human social interaction and the rules and processes that bind and separate people not only as individuals, but as members of associations, groups and institutions.

With this definition of Sociologist and Sociology, we can deduce that the listed statement;

(a. a trend toward seeing the origins and treatments of disease as physical and explicable in scientific terms

b. the acceptance of the hospital as the setting within which to treat serious illnesses

c. the development of the medical profession as a body with codes of ethics and significant social power

d. the requirement that medical training be systematic and long term) are likely what Sociologist will include in the development of medicine.
