There are 250 people at an international medical conference. 50 are africans, 80 are women and 180 are doctors. 20 of the women are Africans, 56 of the doctors are women and 35 of the Africans are doctors. If 10 of the African men are not doctors, how many of the African women are doctors?
35 African docs
50 Africans - 20 women Africans = 30 African men
30 African men - 10 not = 20 African men docs
35 African docs - 20 African men docs = 15 African women docs
To find out how many African women are doctors, we can follow these steps:
Step 1: Start with the total number of African women, which is given as 20.
Step 2: Deduct the number of African men who are not doctors, which is given as 10.
Step 3: Calculate the number of African women who are doctors by subtracting the result from Step 2 from the total number of African women from Step 1.
Step 1: Total number of African women = 20
Step 2: Number of African men who are not doctors = 10
Step 3: Number of African women who are doctors = Total number of African women - Number of African men who are not doctors
= 20 - 10
= 10
Therefore, there are 10 African women who are doctors.
To find out how many of the African women are doctors, we need to first determine the total number of African women, and then subtract the number of African women who are not doctors.
Given information:
Total number of people at the conference = 250
Number of African people = 50
Number of women = 80
Number of doctors = 180
Number of African women who are doctors = 20
Number of women who are doctors = 56
Number of African doctors = 35
Number of African men who are not doctors = 10
To find the number of African women who are doctors:
1. Calculate the number of African women who are not doctors by subtracting the number of African women who are doctors from the total number of African women: African women who are not doctors = Number of African women - Number of African women who are doctors = 50 - 20 = 30.
2. Calculate the number of African doctors who are women by subtracting the number of women who are doctors from the total number of doctors: African doctors who are women = Number of women who are doctors - Number of African women who are doctors = 56 - 20 = 36.
3. Calculate the number of African women who are doctors by subtracting the number of African doctors who are women from the number of African women who are not doctors: African women who are doctors = African women who are not doctors - African doctors who are women = 30 - 36 = -6.
Since we cannot have a negative number of African women who are doctors, it is not possible to determine the exact number based on the given information.
