Question

If Abid works for 8 hours a day, he can complete his work in 6 days. How many hours a day should he work if he wants to finish his work in 4 days?
  1. 6 hours
  2. 8 hours
  3. 9.6 hours
  4. 12 hours


Solution

The correct option is D 12 hours
Here, the number of days taken is inversely proportional to the number of hours worked per day. The total number of hours worked remain the same.

Let 't' be the number of hours per day required to complete the work in 4 days.
Then, 4×t=8×6=48 hours
t=484=12 hours
