Total no. of people attended the festival in all six places = 45000.
 
% of people attended in six different places: 
 


% of people from outside of the state attended the festival in different places:


1
What is the ratio between the no. of people from outside of the state attended the festival in place Agra to that of the in place Faizabad?
» Explain it
C
From the pie-chart and bar graph,

Given, Total no. of people = 45000.

% of people attended the festival in place Agra = 12

So, the total no. of people attended the festival in place Agra

= 45000 ×  12  = 5400
100
 


% of People from outside of the state attended the festival in place Agra = 18

Then, the no. of People from outside of the state attended the festival in place Agra

= 5400 ×  18  = 972
100

% of people attended the festival in place Faizabad = 9

So, the total no. of people attended the festival in place Faizabad
= 45000 ×  9  = 4050
100

% of People from outside of the state attended the festival in place Faizabad = 8

Then, the no. of People from outside of the state attended the festival in place Faizabad
= 4050 ×  8  = 324
100

 Ratio = 972 : 324 = 3 : 1


Hence option C is correct.
 
2
The no. of people from inside of state attended the festival in place Etawah is approximately what percent of the no. of people from inside of the state attended the festival in place Chitrakoot?
» Explain it
A
From the pie-chart and bar graph,

Given, Total no. of people attended  = 45000.

% of people attended the festival in place Etawah = 16

So, the total no. of people attended the festival in place Etawah

= 45000 ×  16  = 7200
100

% of People from outside of the state attended the festival in place Etawah = 35

Then, % of people from inside of the state attended the festival in place Etawah

= 100 – 35 = 65

Hence, the no. of people from inside of the state attended the festival in place Etawah
= 7200 ×  65  = 4680
100

% of people attended the festival in place Chitakoot = 21

So, the total no. of people attended the festival in place Chitakoot
= 45000 ×  21  = 9450
100

% of People from outside of the state attended the festival in place Chitakoot = 28

Then, % of people from inside of the state attended the festival in place Chitakoot = 100 – 28 = 72

Hence, the no. of people from inside of the state attended the festival in place Chitakoot
= 9450 ×  72  = 6804
100

The required % =  [ ( 4680 )  × 100 ] % = 68.78% ≈ 69%
6804


Hence, option A is correct.

3
What is the average no. of people from outside of the state attended the festival in places Agra, Doriae, Etawah, Faizabad?
» Explain it
B
From the pie-chart and bar graph,

Given, Total no. of people attended the festival in all six places = 45000.

Place % of people attended the festival (X) No. of total people attended the festival = X% of 45000
Agra 12 12% of 45000 = 5400
Doriae 32 32% of 45000  = 14400
Etawah 16 16% of 45000 = 7200
Faizabad 9 9% of 45000 = 4050

Now,

Place No. total people attended the festival
(Y)
% of people from outside of the state attended the festival  (A) No. of people from outside of the state attended the festival = Y × (A/100)
Agra 5400 18 18% of 5400 = 972
Doriae 14400 11 11% of 14400 = 1584
Etawah 7200 35 35% of 7200 = 2520
Faizabad 4050 8 8% of 4050 = 324

So, the total no. of people from outside of the state attended the festival in places Agra,

Doriae, Etawah, Faizabad = 972 + 1584 + 2520 + 324 = 5400

The average no. of people from outside of the state attended the festival in places Agra, Doriae, Etawah, Faizabad

5400  = 1350
4

Hence, option B is correct.

Find the difference in the no. of people from inside and outside of the state attended the festival in place Doriae.
» Explain it
A
From the graph and bar graph,

Given, Total no. of people = 45000.

% of people attended the festival in place Doriae = 32

So, the total no. of people attended the festival in place Doriae

= 45000 ×  32  = 14400
100

% of People from outside of the state attended the festival in place Doriae = 11 % of People from inside of the state attended the festival in place Doriae = 100 – 11 = 89

Hence, the difference in the no. of people from inside and outside of the state

attended the festival in place Doriae = 14400 × (89 – 11)%
= 14400 ×  78  = 11232.
100


Hence option A is correct.

5
What is the difference between the average no. of people attended the festival in places Agra, Chitrakoot, Etawah and Banda, Doriae, Faizabaad?
» Explain it
D
From the pie-chart and bar graph,

Given, Total no. of people attended the festival in all six places = 45000.

Place % of people attended the festival (X) No. of total people attended the festival
= 45000 × (X/100)
Agra 12 12% of 45000 = 5400
Banda 10 10% of 45000 = 4500
Chitrakoot 21 21% of 45000 = 9450
Doriae 32 32% of 45000 = 14400
Etawah 16 16% of 45000 = 7200
Faizabad 9 9% of 45000 = 4050

So, the total no. of people attended the festival in places

Agra, Chitrakoot, Etawah = 5400 + 9450 + 7200 = 22050

Then, the average no. of people attended the festival in places Agra, Chitrakoot, Etawah

22050  = 7350
3
And, the total no. of people attended the festival in places

Banda, Doriae, Faizabad = 4500 + 14400 + 4050 = 22950

Then, the average no. of people attended the festival in places Banda, Doriae, Faizabad
22950  = 7650
3

The difference between the total no. of people attended the festival in places

Agra, Chitrakoot, Etawah and Banda, Doriae, Faizabad = 7650 – 7350 = 300.


Hence, option D is correct.
