Calculating the Total Number of Saplings Planted by Students in Three Saturdays

To calculate the total number of saplings planted by the students in three Saturdays, we can follow the given information.

1. On the first Saturday, the students planted 16% of all the saplings. 2. On the second Saturday, they planted 3/5 of the remaining saplings. 3. On the third Saturday, they planted the remaining 504 saplings.

Let's calculate the total number of saplings planted by the students.

Calculation

1. Saplings planted on the first Saturday: - 16% of all the saplings

2. Saplings remaining after the first Saturday: - 100% - 16% = 84%

3. Saplings planted on the second Saturday: - 3/5 of the remaining saplings

4. Saplings remaining after the second Saturday: - Remaining saplings - (3/5 * Remaining saplings)

5. Saplings planted on the third Saturday: - The remaining 504 saplings

6. Total saplings planted: - Sum of saplings planted on the first, second, and third Saturdays

Let's calculate the total number of saplings planted by the students using the given information.

Solution

1. Saplings planted on the first Saturday: - 16% of all the saplings - 16% of X = 0.16X

2. Saplings remaining after the first Saturday: - 100% - 16% = 84%

3. Saplings planted on the second Saturday: - 3/5 of the remaining saplings - (3/5) * 84% of X = 0.504X

4. Saplings remaining after the second Saturday: - Remaining saplings - (3/5 * Remaining saplings) - 84% of X - 0.504X = 0.336X

5. Saplings planted on the third Saturday: - The remaining 504 saplings - 0.336X = 504 - X = 504 / 0.336 - X = 1500

6. Total saplings planted: - Sum of saplings planted on the first, second, and third Saturdays - 0.16X + 0.504X + 504 - 0.16(1500) + 0.504(1500) + 504 - 240 + 756 + 504 - 1500

Therefore, the total number of saplings planted by the students in three Saturdays is 1500.
