Total Books = 100
Fiction = 60, Books less than 350 pages are = 48
Non Fiction = 40, Books less than 30 pages are = 32

total books less than 350 pages = 48 + 32 = 80

Books = 100
Fiction books = 60
Fiction books with less than 350 pages = 80% of 60 = 48
Non-Fiction books = 60
Non-Fiction books with less than 350 pages = 80% of 40 = 32
Total books with less than 350 pages = 48 + 32 = 80

Hence, OA is (E).

Friction books= \(\frac{100*3}{5}\)=60

Non-friction books = 100-60=40

20% of fiction has at least 350 pages which mean 80% of friction books has less than 350 pages

100%= 60
80%= \(\frac{80*60}{100}\)= 48 books of friction has less than 350 pages

And 80% of the non-fiction has less than 350 pages

100%=40
80%=\(\frac{40*80}{100}\)=32 books of Non friction has less than 350 pages

The number of books he released books has less than 350 pages=48+32=80

Total books= 100
3/5 of 100= 60 are Fiction
20% of 60= 12 have atleast 350 pages
So, rest 80% or 60-12=48 have less than 350 pages.

2/5 of 100=40 are Non Fiction
80% of 40 = 32 have less than 350 pages

Total books with less than 350 pages= 48+32=80
