Answer:
In a Book, Odd and Even consecutive page number are always on the same page.
Example – 1 and 2 , 3 and 4 are always on the same page.
First is 7 and 8 – odd and even so they will be on same page. ( 1 page ).
Second – 99 + 100, 101+102 even and odd, so they will on different page ( 2 page ).
Third , 221+222 and 223+224 again even and odd so again on different pages. ( 2 pages ).
Total, 1 + 2 + 2 = 5 pages.
So total Pages that were torn out were 5.
Here’s the Puzzle
A man buys a $10 pair of shoes with a $20 bill.
The store owner doesn’t have any change, so he goes next door to the barber to get change from him.
The store owner returns to his store and gives the man $10 change and his new pair of shoes.
The barber later tells the store owner that the $20 he made change for was counterfeit.
To make up for it, the store owner gives the barber a real $20 bill.
The pair of shoes cost the store owner $5.
How much did the store owner lose after the whole affair?

Here’s the Answer:
The store owner lost $15 in the whole debacle.
Because the counterfeit $20 has no value, the shoe store owner gained $20 when he got change from the barber.
When he then gave the pair of shoes (which costs him $5) and $10 change to the man, he lost $15.
At this point, the owner still has a net gain of $5.
When he pays the barber a real $20 bill to make up for the counterfeit one he gave him earlier, the store owner then lands at a loss of $15 total.
Poor guy.
