Question

if 12 persons compket a work in 12 days how many days will be taken to do by 8 workers

Answer 1

Time taken to complete the work by 12 persons = 12 days
Let the work done by 12 men = 12*12 = 144
Let time taken for 8 persons to do the same work = x days
Therefore work done by persons = 8x
Here work done by 8 men = work done by 12 men
8 x = 144
x = 144/8
x = 18
For 8 persons it will take 18 days to complete the same work.
