Question

out of 150 students appeared in an examination 60% of the students passed in math 50% in Science and 20% in both subjects how many students where failed in both subjects ?by using Venn diagram find the number of student Wawa passed in maths only .​

Answer 1

To find the number of students failed in both subjects, subtract the number of students passed in both subjects from the total number of students. To find the number of students passed in math only, subtract the number of students passed in both subjects from the number of students passed in math.

Step-by-step explanation:

To find the number of students who failed in both subjects, we need to subtract the number of students who passed in both subjects from the total number of students. We are given that 60% of the students passed in math, 50% in science, and 20% in both subjects.

Let's assume the total number of students is 150.

1. The number of students who passed in math = 60% of 150 = 90.
2. The number of students who passed in science = 50% of 150 = 75.
3. The number of students who passed in both subjects = 20% of 150 = 30.

To find the number of students who failed in both subjects, we subtract the number of students who passed in both subjects from the total number of students:

Number of students failed in both subjects = Total number of students - Number of students passed in both subjects = 150 - 30 = 120.

To find the number of students who passed in math only, we subtract the number of students who passed in both subjects from the number of students who passed in math:

Number of students passed in math only = Number of students passed in math - Number of students passed in both subjects = 90 - 30 = 60.
