6 men can complete the electric fitting in building in 7 days how many days will take 21 min to do the same job

Answer 1

hey there,

This problem can be solved by Unitary method.

If 6 men can complete the electric fitting in a building in 7 days,

then 1 man will need 6 x 7 = 42 days to complete it.

Similarly 21 men can complete the job in 42/21 = 2 days.

Hope this helps!

Answer 2

6 men complete it in 7days.
Therefore, 6/3 = 2 men complete it in 21 days.
