D alone can complete half of a work in 100 days. In 47 days what percentage of the work will be completed by D?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 23.5 percent.
D alone can complete half of a work in 100 days.
So, the time required by D to complete the work = 100 × 2 = 200 days
The percentage of the work will be completed by D in 47 days = (47/200) × 100%
= (47/2)%
= 23.5%
Therefore, D will complete 23.5 percent of the work in 47 days.
