Question

10 men can reap a field in 20 days then man reaped the feild for 10 days and after 10 days 10 more men joined them in how many days will the work be finished​

Answer 1

Answer:

Since 10 men worked for 10 days, 10 x 10 = 100 days work is already done. So, 200 - 100 = 100 days of work is left. Thus, total number of days = 10 + 5 = 15.

Answer 2

Answer:

SOLUTION

Total number of work days required =10 x 20 = 200

Since 10 men worked for 10 days, 10 x 10 = 100 days work is already done.

So, 200 - 100 = 100 days of work is left.

Once, 10 more men joined, total number of workers=20

So, number of days required more =

100

20=

5

Thus, total number of days = 10 + 5 = 15.
