At a conference of 100 people. There are 29 india women and 23 india men. Of these india people 4 are doctors and 24 are either men or doctors . There are no foreign doctors. How many women doctors are attending the conference
step pl
is that "men or doctors or both"?
I assume so, since otherwise, all the doctors are women.
It appears that 1 woman is a doctor, since there are only 23 men, 3 of whom are doctors.
To solve this problem, we can use the principle of inclusion-exclusion. Let's break down the problem into smaller parts and gradually find the solution.
Step 1: Total number of Indian attendees
Given that there are 29 Indian women and 23 Indian men, we can calculate the total number of Indian attendees by adding these two values:
Total Indian attendees = 29 (Indian women) + 23 (Indian men) = 52
Step 2: Total number of Indian men or doctors
We are told that 24 out of the total Indian attendees are either men or doctors. We already know that there are 23 Indian men, so we can determine the number of Indian doctors by subtracting 23 from 24:
Total Indian doctors = 24 (total Indian men or doctors) - 23 (Indian men) = 1 (Indian doctors)
Step 3: Total number of women doctors attending the conference
Since there are no foreign doctors, the only doctors at the conference are Indian doctors. We already found that there is 1 Indian doctor, and we also know that there is a total of 4 doctors. Therefore, the remaining 3 doctors must be women:
Total women doctors = 4 (total doctors) - 1 (Indian doctor) = 3 (women doctors)
So, there are 3 women doctors attending the conference.
