According the sum,
36 people were started to work.
6 person were added. so new number of workers = (36+6) 42
starting working hours was 6 hr/ day
2 hrs increased, so they have to work 8 hrs/day.
In the beginning people worked for 12 days,
after increasing heads ,people worked 9days.
there fore total number of people=
120×42/36×8/6×9/12
= 140 men
Ans:- Here total 140 people were working together.
