If 15 people take 5 days to complete a job, in how many days can 25 people finish that work?
Answer & explanation
Correct answer: option 3
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 the value in the formula,
⇒ 15 x 5 = 25 x \( { D}_{2 } \)
⇒ \( { D}_{2 } \) = 3 days,
