Let Cost price be ‘x’.
Selling price = x – 15% of x = 85x /100
85x /100 = 1275
So, x(cost price) = 127500/85 = Rs. 1,500
So, new selling price = 1500 + 10% of 1500
= 1500 + 150 = Rs. 1650
Answer-(D) Rs 1650

(C): 1 : 20 + 170 + 20 = 210
2 : 120 + 70 + 5  = 195
3 : 70 + 200 + 20  = 290
As, 290>210>195

So, 3 > 1 > 2
