उत्तर
Let the number of persons required to fit all the windows in one day be y. The following table is formed.
| Number of persons | 2 | y |
| Number of days | 3 | 1 |
The lesser the number of days, the more will be the number of persons required to fit all the windows. Hence, this is a case of inverse proportion. Therefore,
2 × 3 = y × 1
y = 6
Hence, 6 persons are required to fit all the windows in one day.
