Answer:

105 hamburgers were sold.

Step-by-step explanation:

In order for the number of cheeseburgers to be 3 times the number of hamburgers, the hamburgers must be 1/4 of the total amount sold. 420/4 = 105. This leaves the number of cheeseburgers as 315. 105 x 3 = 315, which proves this is right.
