The ratio of programmers to scientists at a company was 8:5 in the year 2000 and 3:4 in the year 2010. If the total number of programmers and scientists at the company was 52 in the year 2000 and 196 in the year 2010, how many more scientists were at the company in 2010 than in 2000?
In year 2000\(\frac{P}{S} = \frac{8}{5}\)
\(S = \frac{5}{13}(52) = 20\)
In year 2010\(\frac{P}{S} = \frac{3}{4}\)
\(S = \frac{4}{7}(196) = 112\)
The difference is \(92\)
