60 soldier complete 1 work in 1 year
then 1 soldier took 1 year to complete 1/60 part of the work.
1 - 1/60 - time taken 12 month
80 soldier - 80/60 work in 12month
so.. 8/6 work complete by 80 soldier
8 work complete in 72 month
1 work complete in 9month
so...
80 soldier can complete the same work in 9 month
then 1 soldier took 1 year to complete 1/60 part of the work.
1 - 1/60 - time taken 12 month
80 soldier - 80/60 work in 12month
