Answer 1

Answer:

  1990

Step-by-step explanation:

Given In a school election, Peter wins over Albert by a margin of 260 votes which is 13% of the total number of votes. If the invalid votes are 0.5%, then how many votes are valid?

Let  the total number of votes be x

So 13% of x = 260

 13/100 x = 260

 13 x = 26000

x = 2000 votes

So given invalid votes as 0.5%

So 0.5/100 x 2000

 = 10 votes

Now valid votes is 2000 - 10 = 1990 votes

Valid votes is 1990

Answer 2

Answer:

Defective votes = 10

Step-by-step explanation:

Given that

No of votes Peter Wins over Albert = 260

260 accounts to = 13%

So, Total number of votes can be found as

Total Votes = (100x260)/13

Total Votes = 2000

As it is given 0.5% votes are defective. So,

Defective votes = 0.5% of 2000

Defective votes = 0.005x2000

Defective votes = 10
