1) 30%
2) 40%
3) 50%
4) 60%
5) none aff thesee

• 40%
  suppose 1 man do 1% and there is 100 worker
  so total work in previous=100%
  now total work=175%(as increased by 75%)
  working capacity of worker is increased by 25%
  so every worker work 1.25%
  so 100 worker work=125%
  rest work=(175-125)=50%
  50% work can do (50/1.25)=40
  so increnment of no of worker =(40/100)=40%...
