Answer:
3 3/7 days
Step-by-step explanation:
Given
=>
A = 24 days
B = 6 days
C = 12 days
to find = ? how many days they takes to complete the work
now take lcm of 24,6 and 12 we get 24 is the lcm
let us consider that total work is 24 unit
and a takes 24 days to complete to work which mean a can do 1 unit work per day (24/24= 1)
similarly b = 24/6 = 4 unit work per day
c = 24/12 = 2 unit work per day
hance we know the efficiency of all the worker
also we know that
====> total work/efficiency = time taken
where total work is 24 and efficiency is 1+4+3 = 7
so 24/7 = 3 3/7
