Five men can prepare ten toys in six days working six hours a day. Then in how many days can twelve men prepare sixteen toys working eight hours a day?
- Four days
- Three days
- Five Days
- Two days
- Six days
Explanation
We will use the man-hour concept here to solve this problem Formula: (M1 × d1 × h1)/ W1 = (M2 × d2 × h2)/ W2 Where M, d,h, W are numbers of men, number of days, number of hours and work done respectively. Calculation: (M1 × d1 × h1)/ W1 = (M2 × d2 × h2)/ W2 ⇒ (5 × 6 × 6)/10 = (12 × d2 × 8)/16 ⇒ 18 = 6 × d2 ⇒ d2 = 3 ⇒ Number of days to make 16 toys = 3 daysRelated MCQs
