Answer:
x = 6 days.
Step-by-step explanation:
8 men can do a job in 15 Days; Task is 15*8=120
Men-Days; =>
12 men can do the job in 10 Days
12 men can do 3/5 Job in 6 Days
10 women can do the job in 15 days; Task is
15*10= 150 Women-Days;
10 Women can do 2/5 of the job in 6 days
3/5 +2/5=1 Job
In 6 days can 12 men and 10 women do it.
Note:
Let x be the common number of Days for Men
and Women when working together;=>
Equation used: 12 x /120 + 10 x / 150 =( 60 x +40
x) / 600 =x/ 6 of a job; =>
x=6 days.
