From the line graph, we have

Sale of window curtains and door curtains together in store A = 2 * 140 = 280

Let sale of window curtains in store A = 60% of sale of door curtains in store A

(sale of window curtains in store A): (sale of door curtains in store A) = 3: 5

Then, sale of window curtains in store A = 280 * 3/(3 + 5) = 105

And the sale of door curtains in store A = 280 - 105 = 175

Similarly, we can find the data for other four stores as shown below.

Sale of window curtains in store A = 105

And the average sale of door curtains in stores B and D = (200 + 200)/2 = 200

Therefore, difference = 200 - 105 = 95
