The number Mrs. Reno is thinking of is 13

The mystery number is such that when it is multiplied by 7 and then this product is reduced by 6, the result would be 85.

Assume that number is x, the number would be:

(7 × x) - 6 = 85

7x - 6 = 85

7x = 85 + 6

7x = 91

x = 97/7

x = 13

Mrs. Reno is therefore thinking about 13
