Answer:
40
Step-by-step explanation:
given that
20 men decided to complete a work within 30
then the totalwork is 20×30=600
20 men do work in 6days then 20×6=120
then the remaining work is 600-120=480
and also given that after 6 days 8 men affected by illness then the reaming workers are 20-8=12
number of days =reaming work÷ number of persons
number of days=480÷12
=40 days
