The productivity of a team of engineers is given by the function
P(N) = 4000 √N, where N is the total strength. Find the percentage change in productivity if the strength of the team is increased by 1%.
(a) 0.75% (b) 0.5% (c) 0.25% (d) 1% (e) 2%

• let N=100
  P(N) = 4000(sqrt(100))
  
  1% increase -> 101
  so , now P(N) = 4000(sqrt(101))
  
  %change = (sqrt(101) - sqrt(100)) / sqrt(100) = 0.49% = 0.5% approx
