We need to find number of two digit numbers which are divisible by 7.
99/7 = 14.1428...
Thus 14 * 7 = 98 which is the highest two digit number.
14 is the least 2 digit number divisible by 7.
14 = 2* 7
Thus the two digit numbers divisible by 7 are:
2 * 7, 3 * 7,4 * 7, 5 * 7,.... 14 * 7.
Thus number of two digit numbers divisible by 7 is 13.

Originally Answered: How many numbers of two digits are divisible by 7?
The smallest two-digit number divisible by 7 = 14 and the largest two-digit number divisible by 7 = 98. So, it turns out to be an AP series:
14, 21, 28, ……………, 98.
14 + (n - 1)*7 = 98
7n = 91
n = 13
So, the answer is 13.
