hi professor for Q 8 kindly correct me if im wrong

Relation TA contains 10,000 tuples and has 20 tuples per page. =  500 pages
Relation TB contains 3000 tuples and also has 20 tuples per page.= 150 pages
 

the solution says ?

Let M = 10,000 be the number of pages in TA, N = 3,000 be the number of pages in
shouldnt M = 500 in this case and N = 150 ?

 

thank you for the update
