b) 61
c) 168
Step-by-step explanation:
a) In this question it is asked that what is the total of students in class 6A and 6E
- Add the students of class 6A and 6E as shown in pie chart
36 + 28 = 64
c) In this question it is asked that what is total of students in all classes i.e let the students of 6B and 6D be x and the students of 6C is 20, 6A is 36 and 6E is 28.
- 2x = 20 + 36 + 28
- 2x = 84
- x = 84/2
- x = 42
This includes that class 6B and 6D has 42 students each.
Final Answer = 20 + 36 + 28 + 42 + 42
= 168
b) In this question it is asked that what is total of girls in class 6B and 6C
- Add the students of class 6B and 6C and than subtract from 23
- 42 + 42= 84
- 84 - 23 = 61
Final answer
: There are 61 girls in class 6B and 6C

Clarification :
Here, we are given that total number of people who watched the movie are 300. And, 65 % of them liked the movie. We have to finf the number of people who didn't like the movie.
As per the given question, if 65 % liked the movie then rest didn't like the movie. So, 300 people will be considered as 100 % and 65 % liked the movie so 35 % of 300 didn't like the movie. We'll find the 35 % of 300 in order to find the number of people who didn't like the movie.
Explication of steps :
Method ⑴ ::
⪼ Total number of people who watched the movie= 300
⪼ % age of people who liked it = 65 %
If 65 % liked then remain people didn't like the movie. So,
→ % age of people who didn't like = ( 100 % - 65 % ) of 300
→ % age of people who didn't like = 35 % of 300
Now, converting percentage to fraction :
→ Number of people who didn't like the movie = \sf {\Bigg \lgroup \dfrac{35}{ \cancel{100}} \times \cancel{300} \Bigg \rgroup }

→ Number of people who didn't like the movie = \sf {35 \times 3 }35×3
→ Number of people who didn't like the movie = \sf {105 }105

Therefore, Number of people who didn't like the movie are 105.
Method ⑵ ::
⪼ Total number of people who watched the movie= 300
⪼ % age of people who liked it = 65 %
As per the question,
~ Number of people who didn't like = Total number of people – Number of people who liked
→ Number of people who liked = 65 % of 300
→ Number of people who liked = \sf {\Bigg \lgroup \dfrac{65}{ \cancel{100}} \times \cancel{300} \Bigg \rgroup }

→ Number of people who liked = \sf {195 }195
So,
→ Number of people who didn't like = Total number of people – Number of people who liked
→ Number of people who didn't like = 300 - 195
→ Number of people who didn't like = 105
→ \underline{\boxed{\sf{ People_{(Didn't\: like \: movie)} = 105 } }} \: \red{\bigstar}
