18 DAYS = 12 PERSONS.
WORK BY 12 PERSON IN 1 DAY = 12/216 = 1/18
WORK DONE BY 12 PERSON IN 6 DAYS = 6/18 = 1/3 OF TOTAL WORK.
12 PERSONS = 18 DAYS
1 PERSON = 12×18 = 216 DAYS
216 DAYS = 1 WORK
1 DAY = 1/216 WORK
WORK DONE BY 1 PERSON IN 1 DAY = 1/216 WORK.
WORK DONE BY 4 PERSONS IN ONE DAY EQUALS 4/216= 1/24
TOTAL WORK LEFT TO BE DONE = 1/3
WORK DONE BY 4 PERSON IN ONE DAY = 1/24
LET THE TIME TAKEN BE T
THEN 1 / 24 X 3 = 1/3
T/24 = 1/3
T = 1/3 X 24 = 8 DAYS
LEFT OUT WORK WILL BE DONE IN 8 DAYS.
WHICH MEANS,
THEY WILL TAKE 8 DAYS TO COMPLETE THE LEFT OUT WORK.
