If i get 2-3 lessons a day with 8 days of school left and 57 overdue lessons how many lessons do i need to do everyday to catch up.
There are 8 days of school left, so you have 8 days to complete your overdue lessons.
If you need to complete 57 overdue lessons, and you can complete at most 3 lessons per day, you could complete a maximum of 3 lessons x 8 days = 24 lessons in the remaining time.
To catch up on the remaining 57 − 24 = 33 lessons, you need to work on an additional 33 lessons ÷ 8 days = 4.125 lessons per day.
This means you would need to complete at least 5 lessons per day to catch up within the remaining time.
If you need to complete 57 overdue lessons, and you can complete at most 3 lessons per day, you could complete a maximum of 3 lessons x 8 days = 24 lessons in the remaining time.
To catch up on the remaining 57 − 24 = 33 lessons, you need to work on an additional 33 lessons ÷ 8 days = 4.125 lessons per day.
This means you would need to complete at least 5 lessons per day to catch up within the remaining time.
and if i do 10-15 lessons every day in how many days will they be completed
If you complete 10-15 lessons every day, and you have 57 overdue lessons, then you can calculate the number of days required to complete all the lessons as follows:
- If you complete 10 lessons every day, you need 57 / 10 = 5.7 days, which rounds up to 6 days.
- If you complete 15 lessons every day, you need 57 / 15 = 3.8 days, which rounds up to 4 days.
So if you do 10 lessons every day, it will take you about 6 days to complete all the overdue lessons. If you do 15 lessons every day, it will take you about 4 days to complete all the overdue lessons.
- If you complete 10 lessons every day, you need 57 / 10 = 5.7 days, which rounds up to 6 days.
- If you complete 15 lessons every day, you need 57 / 15 = 3.8 days, which rounds up to 4 days.
So if you do 10 lessons every day, it will take you about 6 days to complete all the overdue lessons. If you do 15 lessons every day, it will take you about 4 days to complete all the overdue lessons.
