Answer 1

9514 1404 393

Answer:

10% loss

Explanation:

If Tenzing sold the first watch at 20% profit, his cost c can be found from ...

1200 = 1.20c

1000 = c

If Tenzing sold both watches together for 1200 +1350 = 2550, then his total cost can be found from ...

2550 = 1.02t

t = 2550/1.02 = 2500

Then his cost for the second watch was ...

2500 -1000 = 1500

The sale price of 1350 for that watch represents a multiplier m on the watch cost of ...

1500m = 1350

m = 1350/1500 = 0.90 = 1 - 0.10

Tenzing lost 10% of its cost on the second watch.
