126. Master and apprentice work together to process a batch of parts. If they finish the batch in 3 hours, master processes 60 parts per hour, apprentice works alone in 12.5 days. Ask for this batch of parts 1. The master and apprentice work together to process a batch of parts.

So the rest (12.5 * 24-3) / 12.5 * 24 is equal to 180 of the master's. So the total is 180 divided by the rest of the apprentice. That's 181.81. Obviously, you've missed the information. The apprentice can't work 24 hours a day without eating and drinking

There are 126 pages in a book. On the first day, I read several pages, and on the second day, I read two ninths of the whole book. If the number of pages I have read is the same as the number of pages I have not read, I will read them on the first day

Formula

Let's look at page x on the first day
x+2*126/9=126-x-2*126/9
x+28=126-x-28
2x=70
x=35
I read 35 pages on the first day
