Data regarding voting behaviour in five villages
in block election in year 2014

2015. Also in the year 2015, the number of actual registered voters was 75% of
the total eligible voters the same year. The number of actual registered voters
in village D in the year 2015 was what percent more than that of the same
village in the year 2014?
(b) 0%
(c) 20%
(d) 25%
(e) 30%

village E?
(a) 35:24
(b) 41:30
(c) 35:32
(d) 36:25
(e) 24:25
8.
In the village A, 75% of the actual registered voters were male registered
voters and that of actual female registered voters was 1400, what was the total
population of village A?
(a) 5000
(b) 7200
(c) 7500
(d) 6400
(e) 5200
9.
In village B, the voter’s turnout was 36% of the total population. The voter’s
turnout in village B was what percent of actual registered voters?
(a) 60%
(b) 65%
(c) 70%
(d) 80%
(e) 75%
10.
Total population of village C was 12500 and the voter’s turnout was 80% of the
actual registered voters. What was the voters’ turnout in village C?
(a) 7500
(b) 7200
(c) 6400
(d) 6000
(e) 8000
Solutions:
1. (e), let, female number of students
dropped out = x
Then,
according to the question, [(35090)+(200x)]*25/100 = (350+200)*16/100
Then on
solving we get x= 108
2. (d), according to the question,
[(9x30) + (8x60)] = 4x+3x
Or, 10x= 90
So x = 9
Therefore
number of total students (male +female) = 3x+4x = 7x = 7*9 = 63
3. (e), let, total enrolled students
(male + female) = x
Number of
students dropped out (male + female) = 3x/11
Therefore
number of students (male + female) who complete the course = x3x/11 = 8x/11
Therefore the
percentage of students (male + female) who completed the course and got job = (8x/11)/x
* 100% = 800/11% = 72.72%
4. (a), let the number of enrolled
male students from city C = x
And number of
enrolled female students from city C = y
Percentage of
number of students who got the job = number of students
25% = 96
=> 1% = 96/25 => 100% = 96/25 * 100 = 384
Therefore
number of total students (male + female) who complete the course = 384
Now, total
number of enrolled students (male + female) = 384+52+20 = 456
According to
the question, x+y = 456 and (x52) = (y20)
So equating
both equation, we get x =244
Hence, number
of enrolled male students from city C = 244
5. (e), total number of students (male
+ female) enrolled from city B = 270+210 = 480
Now, number
of students who got the job = 480*40/100 = 192
But in these
192 students include the students also who dropped out.
Therefore
required number of students (male + female) who got the job = 192(33+32) = 127
6. (b), percentage of number of
eligible voters in the village D, in the year 2015 = 60% + 20% = 80%
Number of
actual voter registered in the year 2015 = 75%*80 = 60%
Required % =
6060/60 * 100 = 0%
7. (a), let the population of village
D= x
And the
population of village E = y
Now,
according to the question,
𝑥 ∗ 60% ∗ 60% = 𝑦 ∗ 70% ∗ 75%
On solving we
get x/y = 35/24
8. (a), let the population of village
A = x
Now according
to the question,
𝑥 ∗ 80% ∗ 70% ∗ 75% − 𝑥 ∗ 80% ∗ 70% ∗ 25% = 1400
On solving we
get x = 5000
9. (a), let the total
population of village B = x
Now according
to the question, 𝑥 ∗ 60% ∗ 80% = 36%
Then on
solving x =6/8
Now the
percentage = 6/8*80% = 60%
10. (b), no of voters turnout in
village = 12500 × 80/100 × 90/100 × 80/100 = 7200
