Answer:
12 men can reap the field in a total of 14 days
OR
18 women can reap the field in 14 days
First of all, Taking the case of men
If 12 men does the job in 14 days,then
1 man= 168 days
So, we've to find how many days,8 men will take
that is
168/8=21
So 8 men can do the work in 21 days
Now ,in case of women
18 women can reap the field in 14 days
So, 1 women can do it in = 18×14=252 days
So,for 16 women it is
252÷16=15.75
So,16 women can do the job in 15.75 days
But for total, we've to find how much they will do in 1 day
For men= 1/21
For women= 1/(1575/100)=4/63
So Combining it
1/21+4/63=1/9
so,in 1 day,they can reap 1/9 of the field
So,if the total field is 9
1/9×9=9/9
Therefore they can do the work in a time of 9 days
Answer:
It is given that:-
12men=18 women
=>1man=18/12 women
=>8men=(18/12×8)
•`•8men=12 women
Then,8men+16women = 12 women +16women =28women
A/q
18women=14days
=>1women =(14×8)
=>28women=(14×8/28)
•`•28women =9days
Hence,they need 9 days to complete the work
