If 10 men can make 200 tables working for 15 days at the rate of 8 hr per day, how many tables can 5 men make working for 10 days at the rate of 6 hr a day?
15 days at 8 hr per day = 120 hr.
10 days at 6 hr per day = 60 hr.
So the problem becomes
If 10 men can make 200 tables in 120 hrs, how many tables can 5 men make in 60
hours?
Since 10 men can make 200 tables in 120 hrs, half that many men, or 5 men, can
make only half that many tables, or 100 tables, in that same time, 120 hrs.
Therefore they can make only half that many tables, or 50 tables, in half thst
time, 60 hrs.
Answer 50 tables.
