Answer:

let no. of books in shelf B =100

therefore no. of books in Shelf A=80

on transferring 25% of books from A to B = 80/4=20

i.e =100+20=120

books that are there in A Shelf =60 now

on transferring 25% of books to A is 120/4=30

books that A has = 60+30=90

total number of books =180

%required=

90/180×100=50%
