Please help me solve this easy sounding Story Problem!?

Question

Ben reads x pages a day.
Jane reads 10 more pages a day than Ben.
It takes Jane 10 days to read a book and Ben 12 days to read the same book. How many pages does Ben read?

Answer 1

Let x = number of pages Ben reads each day
then 10+x = number of pages Jane reads each day.

Ben and Jane read the same book, same number of pages

So

12 x = 10(x+10)
12x = 10x +100
2x = 100
x = 50, the number of pages in the book, Both Ben and Jand read the book, so they each read 50 pages!!

Answer 2

Ben reads 50pages a day (x12=600)

jane reads 10more per day than ben (60x10=600)
