Question
The table below shows the total number of registered votes and valid votes in two blocks (A and B) for the years 2012 and 2015.
| Year | Registered Votes in Block A | Registered Votes in Block B | Valid Votes in Block A | Valid Votes in Block B |
|---|---|---|---|---|
| 2012 | 750 | 1200 | 200 | 1000 |
| 2015 | 900 | 1300 | 720 | 1000 |
Note: Number of votes registered in any year = Number of valid votes + Number of invalid votes cast.
Question: What is the percentage difference between the total invalid votes in both blocks in 2015 and the total valid votes in both blocks in 2012? Is it more or less, and by how much percent?
