20 workers working for 5 h per day complete a work in 10 days. If 25 workers are employed to work 10 h per days, what is the time required to complete the work?
Correct Answer: 4 days
Explanation:
Given, M1= 20, M2 = 25, T1 = 5, T2 = 10, D1 = 10 and D2 = ?
According to the formula,
M1T1D1= M2T2D2
⇒ 20 x 5 x 10 = 25 x 10 x D2
∴ D2 = 20 x 5 x 10/25 x 10 = 4 days
