C

Step-by-step explanation:

In the first instance, he wanted buying euros in exchange for his dollars. He had $540 and wanted to buy euros. The conversion factor here is that for every 1 euro, he pays $1.80

Now at the second instance, he wanted buying dollars with his left over euros. This means for every 1 euro, he gets $1.4

Since, he is having 40 euros, the total amount in dollars he would get will be 40 * $1.4 = $56
