The table shows the city bus schedule for certain bus lines. Bus LineArrives at thebus stop every...A25 minutesB15 minutesBoth buses are at the bus stop right now. In how many minutes will both buses be at the bus stop again?

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
