10 % of the electorate did not cast their votes in an election between two candidates. 10 % of the votes polled were found invalid. The successful candidate got 54 % of the valid votes and won by a majority of 1620 votes. The number of voters enrolled on the voter’s list was___________?

A. 25000
B. 33000
C. 35000
D. 40000
Explanation:
Let the number of votes enrolled be x
Votes cast = (90/100 × x) = 9x/10
Valid votes = 90% of 9x/10 = (90/100 × 9x/10) = 81x/100
Votes polled by successful candidate
= (54/100 × 81x/100) = 4374x/10000
Votes polled by defeated candidate
= (46/100 × 81x/100) = 3726x/10000
=> 4374x – 3726x = 16200000
=> x = 16200000/648 = 25000

A. 10000
B. 16400
C. 16800
D. 18000
Explanation:
Let the enrolled votes be x,
Votes cast = (75/100 × x) = 3x/4
Valid votes = (98/100 × 3x/4)
= 147x/200 75/100 × 147x/200 = 9261
=> 441x = (9261 × 800)
=> x = 16800

Explanation:
Valid votes = (80/100 × 7500) = 6000
Valid votes polled by one candidates
=(55/100 × 6000) = 3300
Valid votes polled by another candidate

A. 21000
B. 2200
C. 23500
D. 27500
Explanation:
Let the total number of voters be x
Votes cast = 92 % of x = (92/100 × x) = 23x/25
Votes in favour of winning candidate = 48/100 × x
= 12x/25
Votes polled by defeated candidate = (23x/25 – 12x/25)
= 11x/25 12x/25 – 11x/25 = 1100
=> 12x – 11x = 27500
=> x = 27500

Mathematics Mcqs, Percentage Mcqs /
The sum of two numbers is 2490. If 6.5 % of one number is equal to 8.5 % of the other then the numbers are:_________?

A. 989, 1501
B. 1011, 1479
C. 1401, 1089
D. 1411, 1079
Explanation:
Let the number be x and (2490 – x).
Then 6.5 % of x = 8.5 % of (2490 – x)
=> 6.5/100 × x = 8.5/100 × (2490 – x)
=> 65x/1000 = 85(2490 – x)/1000
=> 65x = (85 × 2490) – 85x
=> 150x =(85 × 2490)
=> x = 211650/150 = 1411
Hence the numbers are 1411 and (2490 – 1411) = 1079
