If 25 men can complete a work in 36 hours, then in how many hours will 12 men complete the same work?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 75.
Formula used:
M1 × T1 = M2 × T2 ----- (1)
Where M1 and M2 = Number of person and
T1 and T2 = Time
Calculations:
Using equation (1), we get
⇒ (25 × 36) = (M2 × 12)
⇒ M2 = (25 × 3) = 75
