If 3 men or 6 boys can complete a task in 20 days, how many days will 6 men and 8 boys take to do the same task?
Answer: 6
Explanation
Let's solve:
3 men = 6 boys (given)
1 man = 2 boys
Work done by 3 men or 6 boys in 20 days:
Let's calculate work done by 1 boy in 1 day:
6 boys * 20 days = 120 boy-days
Now, 6 men and 8 boys:
6 men = 6 * 2 = 12 boys
Total = 12 boys + 8 boys = 20 boys
Time taken = 120 boy-days / 20 boys = 6 days
