Question

8 men works for 8 days and 8 houes each day do 12 unit of work then how much work does 6 men for 6 days and 6 hours each does

Answer 1

here, for 8 men,
they work for 8 days and 8 hours each day.
then they need time totally 8*8=64 hours
And, for 6 men,
they work for 6 days and 6 hours each day
then they need time totally 6*6=36 hours

Now,
8 men need 64 hours to do 12 unit of work
then 1 man needs 64*8=480 hours to do 12 unit of work
then 6 men needs 480/6=80 hours to do 12 unit of work

If
80 hours are needed to to do 12 unit of work
then 36 hours are needed to do 12*36/80=5.4 unit of work
So 6 men will do 5.4 unit of work for 6 days and 6 hours each
