Given : A rural library created lending facilities for only 100 books and kept the lending desk open only on Mondays.

To Find : How many books outside after stock check on M3
Solution:
Initial Stock = 100
M1 books lent = 80
Hence stock remained = 100 - 80 = 20
on M2
Book returned = 50
Books lent = 60
Hence Stock = 20 + 50 - 60 = 10
on M3
Book returned = 80
Books lent = 40
Hence Stock = 10 + 80 - 40 = 50
Books in Stock = 50
books outside after stock check on M3 = 100 - 50 = 50
so 50 books outside after stock check on M3
