Answer 2

Given:

• $7$ persons cleans $7$ classrooms in $7$ days using $7$ buckets.

To find:

• How many days will it take if $5$ persons cleans $5$ classrooms using $5$ buckets.

Step by step explanation:

• We know that $7$ persons can clean $7$ classrooms in $7$ days using $7$ buckets.
• So $1$ person uses only one bucket to clean one classroom for $7$ days.
• If every $1$ person uses only $1$ bucket they will clean $1$ classroom in $7$ days.
• That is if each and every one person uses only $1$ bucket every one of them will clean a classroom in $7$ days.
• If seven persons work together to clean each and every classroom with one bucket they will clean seven classroom in seven days.

• Thus $7$ classrooms will be cleaned in $7$ days.

• Similarly, if $5$ person cleans $5$ classrooms using $5$ buckets then, they will clean $5$ classrooms in $5$ days.

Final answer:

• Therefore $5$ persons can clean $5$ classrooms using $5$ buckets in $5$ days.
