Candidate A and B participate in a election.10% is invalid vote . 'A' won by 20% more than B total voters are 10,000 .Find given vote of the B ?​

Answer 1

Answer:

Let the number of votes A gets =x

Then, by the given condition,

the number of votes B gets =x−308.

60 votes were invalid.

∴ The total number of votes polled =x+x−308+60=2x−248.(i)

10% of the listed population refrained from voting.

∴ (100−10)%=90% of the listed population took part in the election.

So, the total number of the listed population = (2x−248)×

90

100

=

9

20x−2480

.

47% of this population voted for A.

∴ A got

9

20x−2480

×

100

47

=x

⇒47(20x−2480)=900x

⇒40x=116560

⇒x=2914

So, the total number of votes polled =2x−248 ..(from i)

= 2×2914−248=5580
