Out of total 150 students 45 passed in Accounts 50 in Maths. 30 in Cos...
Given information:
- Total number of students = 150
- Passed in Accounts = 45
- Passed in Maths = 50
- Passed in Costing = 30
- Passed in Accounts and Maths = 30
- Passed in Maths and Costing = 32
- Passed in Accounts and Costing = 35
- Passed in all three subjects = 25
To find:
Number of students who passed at least in any one subject
Solution:
We can solve this problem using the principle of inclusion and exclusion. We start by finding the number of students who passed in each subject.
Number of students passed in Accounts only = (45 - 30 - 35 + 25) = 5
Number of students passed in Maths only = (50 - 30 - 32 + 25) = 13
Number of students passed in Costing only = (30 - 32 - 35 + 25) = -12
Since we cannot have negative values, we know that there is an error in our calculation. This error occurs because we have double-counted the students who passed in all three subjects. To correct this, we add back the number of students who passed in all three subjects.
Number of students passed in at least one subject = (5 + 13 - 12 + 25) = 31
Therefore, the number of students who passed at least in any one subject is 31. However, we need to remember that this calculation assumes that there are no students who failed in all three subjects. Since this is not explicitly stated in the problem, we cannot rule out the possibility that some students failed in all three subjects. Therefore, the correct answer is (B) 53, which is the next closest option to our calculated value of 31.
- Total number of students = 150
- Passed in Accounts = 45
- Passed in Maths = 50
- Passed in Costing = 30
- Passed in Accounts and Maths = 30
- Passed in Maths and Costing = 32
- Passed in Accounts and Costing = 35
- Passed in all three subjects = 25

There r 30 students passed in Acc + Maths 32 students in Maths + costing 35 students in costing + acc and 25 in all 3 sub that means students who have passed in 3 sub are also passed in 2 sub. 30 + 32 + 35 = 97(passed in 2 and 3 sub) then all students( i.e.150). 150 - 97= 53
