Answer 1

Answer:

At the end of first yr , workers left = 8000*5/100 = 400

workers started at second yr = 8000-400 = 7600

again 5% left = 7600*5/100 = 380

workers start in 3rd yr = 7600-380 = 7220

now, at the end of third yr workers were inc by 10% to complete the job .

workers added = 7220*10/100 = 722

Workers during 4th yr = 7220+722 = 7942 (Ans)
