How many times does the number "9" appear in the page numbers of a 100-page newspaper? Choose from

the possible answers below.

( )9

( )10

( )15

( )19

( )20

( )21

Unless this is a trick question that I have missed, there should be 11 times that the

number "9" appears:

9, 19, 29, 39, 49, 59, 69, 79, 89, and twice in 99 = 11 "9's"

"11" is not a possible choice.

Is there something special about the numbered pages of a newspaper that would affect this answer?

Or are they considering that the "99"

has only one number 9 since the first

9 would represent 90?

I got 11 too. There is probably a trick but I do not get it. Perhaps they are counting upside down 6 or something.

I think you forgot

90, 91, 92, 93, 94, 95, 96, 97, and 98.

I get 20 times.
