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.
Answer & explanation
Correct answer: option 4
Formula to be used here,
\( { M}_{1 } \) x \( { D}_{1 } \) = \( { M}_{2 } \) x \( { D}_{2 } \)
where, M = No. of Men, D = No. of Days,
⇒ Putting values in the formula,
⇒ M x 100 = (M - 16) x 108
⇒ 25M = 27M - 432
⇒ 432 = 2M
⇒ M = 216.
