In a class of 40 students,30 takes agric science and 20 takes physics.If 8 takes neither agric nor physics.How many offers agric and not physics
If x take both, then
30+20-x = 40-8
x = 18
So 30-18 = 12 take only agsci
Well, it seems like we have a lot of student farmers in that class! Let's crunch some numbers.
We have 40 students in total. Out of those, 30 take agric science and 20 take physics. However, we need to subtract the 8 students who take neither agric nor physics.
So, to find out how many students take agric and not physics, we can subtract the number of students taking physics (20) from the total number of students taking agric (30).
30 - 20 = 10
Therefore, 10 students offer agric science and not physics. They must be planting all the jokes in the classroom!
To find out how many students take only agricultural science (agric) and not physics, we first need to determine the number of students who take both subjects and subtract that from the total number of students taking agric science.
Given:
Total number of students in the class (n) = 40
Number of students taking agric science (Agric) = 30
Number of students taking physics (Physics) = 20
Number of students taking neither agric nor physics = 8
To find the number of students taking both agric and physics, we use the principle of inclusion-exclusion.
Number of students taking both agric and physics = (Number of students taking agric) + (Number of students taking physics) - (Number of students taking neither)
Number of students taking both agric and physics = 30 + 20 - 8 = 42
Now, we can find the number of students taking only agricultural science using the formula:
Number of students taking only agric = Number of students taking agric - Number of students taking both agric and physics
Number of students taking only agric = 30 - 42 = -12
Since it is not possible to have a negative number of students, it seems there is an error in the given information or calculations. Please recheck the data or calculations provided.
To find out how many students offer Agriculture Science (agric) but not Physics, we need to use the principle of inclusion and exclusion.
Let's start by finding the number of students who take both Agriculture Science and Physics.
From the given information, we know that:
- The number of students taking Agriculture Science (agric) = 30
- The number of students taking Physics = 20
- The total number of students in the class = 40
To find the number of students who take both subjects, we add the number of students taking each subject and then subtract the total number of students in the class:
30 (agric) + 20 (physics) - 40 (total students) = 10
Now, let's find the number of students who take Agriculture Science but not Physics.
Since we know that the number of students taking both subjects is 10, we subtract that from the number of students taking Agriculture Science:
30 (agric) - 10 (agric and physics) = 20
Therefore, there are 20 students who offer Agriculture Science (agric) but not Physics.
