Given,
A builder employed 4000 workers to work on residential project. At the end of the first year 10% workers were removed. At the end of the second year 5% of those working at that time were retrenched. However to complete the project in time, the number of workers was increased by 15% at the end of the third year.
To Find,
How many workers were working during the 4th year?
Solution,
No. of workers at the beginning = 4000
No. of workers at the end of first year = 4000 - (10% of 4000) = 4000 - 400
= 3600
No. of workers at the end of second year = 3600 - (5% of 3600)
= 3600 - 180 = 3420
No. of workers at the end of third year = 3420 + (15% of 3420)
= 3420 + 513 = 3933
Hence, 3933 workers were working during the 4th year.
