89 - 10 = 79
89
89 + (5 x 10) = 139
Possibility of two digit no whose sum is 17. 89 and 98. Reverse of 98 is 89. The no 89 is 9 less than the no 98. So 98 is original no,89 is new no.
To total 17 the two digits must be 8 and 9! The original number was 98.
97.97 is less than 100 and more than 89.the tens digit (which is 9) is two more than the ones digit (which is 7)
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.
