It is 2500.
The sum of all the digits of all the positive integers that are less than 100 is 4,950.
The integers greater than 10 but less than 100 start from 11 and go up to 99. To find the count of these integers, subtract 10 from 99, which gives 89, and then subtract 1 (to exclude 10 itself), resulting in 89 - 10 = 89. Thus, there are 89 integers greater than 10 but less than 100.
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
There are 20.
81
8 of them.
The squares -- nine of them.
