Applying the first discount, the buying price would have been
85% of 1500 = 85/100 x 1500 = 1275
Let the second discount be x%
The final buying price = (100-x)/100 x 1275 = 1173
(100-x)/100 = 1173/1275 = 0.92
100-x = 0.92x100 = 92
-x = 92-100
-x= -8
x = 8%
The rate of the second discount was 8%
85% of 1500 = 85/100 x 1500 = 1275
Let the second discount be x%
The final buying price = (100-x)/100 x 1275 = 1173
(100-x)/100 = 1173/1275 = 0.92
100-x = 0.92x100 = 92
-x = 92-100
-x= -8
x = 8%
The rate of the second discount was 8%
