Last year, we strengthened our commitment to innovation by doubling the rate of increase of spending for basic and applied research, compared to the rate in the year before. ​

For example, if spending for basic and applied research was $100,000 in 2007 and $125,000 in 2008, the rate of increase was 25%.

If the rate of increase doubled in 2009, then it would be 50%. (Thus, spending on research would be $125,000 + 50% = $187,500.)

I'm not a mathematics expert, so I hope this made sense! :roll:

Hello Everyone, ​

Rate of increase is a mathematical term but mostly used to derive economic parameters such as rate of economic growth/inflation/population growth etc.
· The formula is: Rate of increase = Total number of increase / Total time

e.g.
Population of city A is 150000 in Year 2005 and 180000 in Year 2008.
The rate of increase is (Total number of increase-180000 – 150000=30000) / (Total time-2008 – 2005=3)
= 30000 / 3 = 10000 people per year
If you need the rate of increase per month:
30000/ (3x12) = 30000 / 36 = 833.33 people per month

Here is a chart showing growth of population in Indian sub-continent calculated from per year to per minute

Rate of Increase in Indian Population
Per Year ....................1,55,31,000
Per Month ...............12,73,033
Per Day ....................42,434
Per Hour ..................1,768
Per Minute ..............29
