# If 14 typists typing 6 hours a day can take 12 days to complete the manuscript of a book, then how many days will 4 typists, working 7 hours a day, can take to do the same job?

Answer :

Given: Number of days required for 14 typists to type the manuscript 6 hours a day = 12 days

To find: Number of days required for 4 typists to type working 7 hours a day.

14 typists work 72 hours to complete the manuscript of a work.

14 typists complete of the manuscript in 1 hour.

1 typist completes of the manuscript in 1 hour.

4 typists complete 4× of the work in 1 hour.

4 typists complete 6× of the work in 6 hours per day

It will take = 42 days for 4 typists to complete the whole manuscript.

∴ Number of days required for 4 typists to type working 7 hours a day is 42 days.
