Question

12 men can do a work in 10 days while 10 women can do the same work in 18 days in how many days 4 men and 6 women together can do the same work?​

Answer 1

Answer:

12men=10 days

1man=10/12

4men=(10/12)*4

=10/3

10women=18 days

1 women=18/10

6 women=(18/10)*6

=54/5

so 4 men and 6 women together work for=(10/3)+(54/5)=14²/15

Answer 2

Answer:15

Step-by-step explanation:

1 man -> 12*10 = 120 days

1 woman -> 10*18 = 180 days

eff of man and woman

for total work we take lcm of 120 & 180 , we get 360 now divide it by days of one man and woman

we will get 3 and 2 this is man and woman's per day work respectively

now multiply this with the asked data in ques i.e 4 men + 6 women -->

4*3+6*2= 24 this is eff now divide total work with it to get the ans 360 by 24 =15{ans}
