B works for 5 days and takes rest on the next two
days and C works for 7 days and takes rest on the
next three days. If A, B and C work at the same rate
in how many days will the work be completed?​

Answer 1

Answer:

when men A work = 3 days

he take rest on 4 th day

men B start work on the 4th day for 5 days

total days elapsed = 3 + 5 = 8

now , 30 - 8 = 22 days are left

now men B rest for 2 days

now only 20 days are left

Men C work on the second day for 7 days on which men B take rest

now 13 days are left

he takes rest for four days

now 9 days are left

the days in which the work completes is 30 - 9 = 21

the work get completes in 21 days
