A work could be completed in 100 days by some workers. Due to the absence of 16 workers, the work was completed in 108 days. Find the original number of works.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 216.
Concept used:
M1 × D1 = M2 × D2 ----- (1)
Where M and D are the number of men and days
Calculations:
Let the number of men be x
According to the question;
⇒ x × 100 = (x - 16) × 108
⇒ 25x = 27x - 27 × 16
⇒ 2x = 27 × 16
⇒ x = 27 × 8 = 216
