Question

If 6 man and 9 women can do a piece of work in 15 days,how long will 12 women and 6 men take to do it ?​

Answer 1

Answer:

6man do work= 15 days

1 man do work=15/6

6 men do work=(15/6)*6

=15 days

9women work=15 days

1 women work=15/9

12 women work=(15/9)*12

= 20 days

now 6 men and 12 women work=15+20=35 days (ans)
