Answer:
5% loss.
Step-by-step explanation:
To get a 10 % profit , by proportion the original cost of the watch was 495 / 1.1
= 450.
For the 10% loss the original cost was 495 / 0.90 = 550.
So he sold 2 watches which originally cost for 550 + 450 = 1000 for 2*495
= 950 and the loss was (50 / 1000) * 100 = 5%.
