Two method to solve.
1. Guess and check
2. Assumption method.
I use assumption method.
Assumed all are small buses.
42 x 15 seats = 630 seats
1055 - 630 = 425 seats balance.
Large bus 40 - small bus 15 = 25 seats different.
Therefore, large bus = 425/25 = 17 large buses.
Ans: Adam book 17 large buses.
Hope this helps
