Question

In an election between two candidates A and B 20% did not participate in voting 200 casted not declared invalid and when you got 60% of valid votes and won by 600 votes Find the no. of voters participate in voting?

Answer 1

Number of voters who participated `=1200`

Explanation:

Number of people eligible to vote `=x`
Number of people didn't participate `x xx 20/100=0.2x`

Number of people who voted `=x-0.2x=0.8x`

Invalid votes `=200`

Number of valid votes `=0.8-200`

Votes in favour `=(0.8x-200)xx60/100`
`(0.8x-200)xx60/100=600`

`0.48x-120=600`
`0.48x=600+120=720`
`x=720/0.48=1500`

Number of eligible voters `=1500`
Number of voters didn't parcipate `=1500 xx 0.2=300`

Number of voters who participated `=1500-300=1200`
