Total Cost price = 300*19 +200*10 +10*10 = 5700+2000+100 = 7800
Total Selling price = 400*20 + 110* 15 = 8000+1650= 9650
So profit = 9650-7800 = 1850
Using property log ab cd = d/b log ac we get -3/-1 logYX = 3Z

Let 6518-x is divisible by 36
36=4*9
So number should be divisible by 4 and 9
(18-x) divisible by 4
X=2
6+5+1+8=20
20-x divisible by 9
X=2
Hence x=2
