Ticket Combinations

How are tickets issued on buses? Suppose that I have to purchase tickets worth Rs. 20/-. Why is it that I am given a combo of Rs. 19/- + Rs.1/- ticket. Why not 15+5 or 10+10?

The other tickets are also there in the box. So, why the preference for this 19+1 combo?

Any answers?
