Answer:
The answer is €375.
Step-by-step explanation:
If the exchange rate is $1.55 per € then €10,000 is equal to $15,500. At $120 per share, you can but 129 shares for $15,500.
And if you sell those 129 share at $135 per share, then your total comes up to $17,415. If the exhange rate had stayed the same, that would be €11,235 just for the increase in the prices of the shares. But the exhange rate is $1.50 per € so the amount after selling the shares is €11,610. The difference the exhange rate makes is €11,610 - €11,235 = €375.
I hope this answer helps.
