B alone can complete half of a work in 150 days. In 30 days what percentage of the work will be completed by B?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 10 percent.
B alone can complete half of a work in 150 days
B can complete the whole work = 300 days
Work done by B in 1- day = 1/300
Work done by B in 30 days = 30 × 1/300 = 1/10
Thus, the work completed in 30 days is 10%.
