To finish a work in 12 days, 8 workers are engaged. After 2 days, due to some urgency, the work is to be finished in the next 2 days. How many more workers are to be engaged now to finish it on time?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 32.
To finish a work in 12 days, 8 workers are engaged
Total work = 8 × 12 = 96 units
In the first 2 days, 8 workers will work
Work done = 8 × 2 = 16 units
Remaining Work = 96 - 16 = 80 units
Let the total number of workers required be x
⇒ x × 2 = 80
⇒ x = 80/2
⇒ x = 40
Additional Workers = 40 - 8 = 32
So, 32 more workers are needed to finish the work on time
