arithmetic - 6 men and 4 women can make 150 bags in in 8 days while 7 men and 3 women can complete it in 10 days in how many days will 25 men can make 150 bags - skillgun

Solution : Let 1 man's 1 day's work = x and 1 woman's 1 day's work = y.
Then, 6x + 4y = 1/8 and 7x + 3y = 1/10.
Solving these two equations, we get : x =1/400, y =11/400.
.'. 1 man's 1 day's work = 1/400.
=> 25 men's 1 day's work = (1/400 * 25) = 1/16.
Hence, 25 men will make 150 bags in 16 days.
