Answer 1

3 typists : 7 hours a day : 10 days (Given)

.

Find 1 typist:

3 ÷ 3 typists : 7 hours a day : 10 x 3days

1 typist : 7 hours a day :30 days

.

Find 2 typists:

1 x 2 typists : 7 hours a day :30 ÷ 2 days

2 typists : 7 hours a day : 15 days

.

Find 1 day:

2 typists : 7 x 15 hours a day : 15 ÷ 15 days

2 typists : 105 hours a day : 1 days

*The solution of 105 a day may not be logical but it is a intermediate working, so we leave it as it so that we can work on it later.

.

Find 12 days:

2 typists : 105 ÷ 12 hours a day : 1 x 12days

2 typists :8.75 hours a day : 12 days

.

Answer: The 2 typists will have to work for 8.75 hours a day for 12 days.
