the library has a total collection of 2630 books. the number of non-fiction books is 240 fewer than the number of fiction books but 190 more than the number of picture books. how many books of each type are there in the library?



Answer :

let the no of non fiction books be x
so, no of fiction books = x+240
and no of picture books = x -190
total no of books = x+x+240+x-190 = 2630
or, x = 860 = no of non fiction books
no of fiction books = 860+240 =1100
no of picture books = 860-190 = 670
