B1. Above the campsite where Huub is camping, there is a cable car with $n$ numbered gondolas.

The gondolas hang in a loop at equal distances from each other. After gondola 1 comes gondola 2, after gondola 2 comes gondola 3, and so on, and after gondola $n$ comes gondola 1 again. At a certain moment, Huub looks straight up and sees gondolas 42 and 94 passing right next to each other, with 42 moving to the left and 94 moving to the right. A while later, Huub looks up from the same spot again and sees gondolas 185 and 35 passing next to each other, with 185 moving to the left and 35 moving to the right.

What is $n$?
B1 When Huub looks for the first time, he sees the situation below where in the right part of the loop, the gondolas $43 \mathrm{t} / \mathrm{m} 93$ are located. That's a total of 51 gondolas.

When Huub looks for the second time, he sees the situation below where now in the left part of the loop, the gondolas $36 \mathrm{t} / \mathrm{m} 184$ are located. That's a total of 149 gondolas.

In total, there are thus $51+149+2=202$ gondolas.
