Direction for question $71$ to $75$:
Study the pie-chart carefully to answer the question that follows. Percentage distribution of students in different courses. A total number of students $ = 6500$ what is the total number of students in B.Ed., Pharmacy and MBBS together.

Hint: Whole pie is given in the percentage so we will compare $100\% $ with the given total value so we will get the value of the $1\% $ which we will put in the pie chart then we will get our required value.

Complete step by step Solution:
Given the pie chart is given in the form of percentage and the total number of students $ = 6500$
So now we will compare $100\% $ with the $6500$ then we will get the value of $1\% $
$ \Rightarrow 100\% = 6500$
So, the value of $1\% = 65$ which we will use for the required answer
Now according to the question, we need to find the value of the total number of students in B.Ed., Pharmacy, and MBBS together.
So in the pie chart, we can see the value of B.Ed students in the form of percentage is the $18\% $
Now we know the value of $1\% $ then the total number of students in the B.Ed is the $18 \times 65$
After multiplication, we will get the total number of the students in the B.Ed is the $1170$
Now the total number of students in the Pharmacy is $13 \times 65$
After multiplication, we will get the total number of the students in the Pharmacy is the $845$
Now the total number of students in the MBBS is $6 \times 65$
After multiplication, we will get the total number of the students in the MBBS is the $390$
the value of the total number of students in B.Ed., Pharmacy, and MBBS together
$ = 1170 + 845 + 390$
After addition, we will get our value of the total number of students
$ = 2405$

Therefore, the value of the total number of students in B.Ed, Pharmacy, and MBBS together is $2405$.

Note:
In these types we have to check out the form of a pie chart because the pie given in various forms so first, we have to check out the form of a pie chart then compare it with the given total value and solve it by putting values.
