A man sold two watches, each for 495. If he gained 10% on one
suffered a loss of 10% on the other, then what is the loss or gain percen
transaction?
(a) 1% gain
(b) 1% loss
100
(c) - % loss
(d) Neither gain nor loss
(e) 99

d neither loos nor gain

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%.
