Question

20 men can complete a piece of work in 10 days but after every 4 days 5 men are called off. In what time will the work be finished ?​

Answer 1

Answer:

Step-by-step explanation:

15 days

Answer 2

The work will be finished in 8 days.

Step-by-step explanation:

Since we have given that

Number of men = 20

Number of days = 10

After 4 days , 5 men are caled off,

so, it becomes,

$20\times (10-4)=15\times d\\\\20\times 6=15\times d\\\\\dfrac{120}{15}=d\\\\d=8\ days$

Hence, the work will be finished in 8 days.
