Question: Some persons can do a piece of work in 24 days. Two times the number of such persons will do half of that work in -

Solution:
Let the initial workers be x
So, workers for 2nd time = 2x

x persons can complete 1 part in 24 days
1 person can complete 1 part in 24x days
2x persons can complete 1/2 part in 24x/(2x × 2) days
= 6 days
