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.

In store E:

Total number of curtains sold = 500

Number of blue colour curtains sold = 65% of 500 = 325

And the number of blue colour window curtains sold = 1/5 of 325 = 65

Then, number of blue colour door curtains sold = 325 - 65 = 260

Therefore, number of door curtains sold that are not blue = 400 - 260 = 140
