5 men or 8 boys can harvest the field in 16 days.

In how many days can 15 men and 8 boys harvest the field?​

Answer 1

Answer:

9 days

Step-by-step explanation:

12 men or 18 women can reap a field in 14 days, how many days will 8 men and 16 women take to reap it?

Let the amount of task for reaping a be 100%=1

Given 12 men OR 18 women can reap a field in 14 days

∴ In 1 day, 12 men OR 18 women can do 114 of the total work.

∴ 1 man OR 1 woman can do 114×12 and 114×18 ie 1168 and 1252 of the total work respectively.

∴ in 1 day, 8 men and 16 women do 8(1168)+16(1252) ie 19 work.

19 work in 1 day

⇔ 1(ie complete) work in 119=9days .

∴ 8 men and 16 women can reap a field in 9 days.
