Let's first calculate the total work required to build 3 huts in 21 days.
Total work = 3 huts
Let's assume each hut is equivalent to 1 unit of work.
So, total work = 3 units
Now, let's calculate the work done by 5 people in 21 days:
Work done by 5 people in 21 days = 5 * 21 = 105 people-days
Now, let's find the work done by 1 person in 1 day:
Work done by 1 person in 1 day = Total work / Total days
Work done by 1 person in 1 day = 3 / 105 = 1/35 units
Now, let's find the number of people required to build 6 huts in 15 days:
Total work = 6 huts
Total work = 6 units
Work done by 1 person in 1 day = 1/35 units
Let the number of people required be x.
Work done by x people in 15 days = x * 15 * (1/35) = 6
Solving for x:
x * 15 * (1/35) = 6
x * 15 = 6 * 35
x = (6 * 35) / 15
x = 14
Therefore, 14 people working at the same rate can build 6 similar huts in 15 days.

Given:
- 5 people build 3 huts in 21 days
- Number of huts built = 3
- Number of days taken = 21
- Number of people = 5
To find:
- Number of people required to build 6 huts in 15 days
Step 1: Find the work done by 5 people in 1 day.
Work done = Number of huts built - Number of days taken
Work done = 3 - 21 = 63 units
Step 2: Calculate the work required to build 6 huts in 15 days.
Work required = Number of new huts - Number of new days
Work required = 6 - 15 = 90 units
Step 3: Calculate the number of people required to do the work.
Number of people = Work required / Work done by 5 people in 1 day
Number of people = 90 / 63 =
10 people
Therefore,
10 people
working at the same rate will build 6 similar huts in 15 days.
