It is 2500.
The sum of all the digits of all the positive integers that are less than 100 is 4,950.
Sum of all such integers less than 100 would be 416 .
There are 80 such integers.
Because 23 counting integers out of 100 ( .23 = 23/100 ) is certainly more than 13 counting integers out of 100 ( .13 = 13/100 ) 4.23 > 4.13 ---------------
32
All of them from 45 to 99 ... 55 integers.
I'm assuming the question should read n greater than 10 and less than 100 and there are 8 numbers that satisfy this,1223344556677889So the answer is dhttp://www.webanswers.com/share-question.cfm?q=how-many-integers-n-greater-than-and-less-than-100-are-there-such-that-if-the-digits-of-n-are-the-is-1379ff| http://www.webanswers.com/answer/1566078/education/how-many-integers-n-greater-than-and-less-than-100-are-there-such-that-if-the-digits-of-n-are-the-is-1379ff| http://www.webanswers.com/report-abuse.cfm?q=how-many-integers-n-greater-than-and-less-than-100-are-there-such-that-if-the-digits-of-n-are-the-is-1379ff&p=1566078
The squares -- nine of them.
There are 20.
8 of them.

Integers which are the squares of integers are called perfect squares or square numbers. Perfect squares less than 101 are 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100.
