Practice Question 6 men can complete a work in 10 days. They start the work and after 2 days 2 men leave. In how many days will the work be completed by the remaining men?
Let’s say the total work to be completed is represented by “W.”
Initially, 6 men are working, and they can complete the work in 10 days. This means in one day, they collectively complete 1/10th of the work, which we can represent as (1/10)W.
After 2 days, they have completed (1/10)W * 2, which is (2/10)W or (1/5)W.
Now, 2 men leave, so you have 4 men remaining.
You want to find out how long it will take the 4 remaining men to complete the remaining work, which is (4/5)W.
To solve this, think about how much work the 4 men do in one day, and then you can find out how many days it will take them to complete (4/5)W.
