A pizza shop sells only two types of pizza: Margarita and Pepperoni. On a particular day, the shop sold 70 Margaritas and 100 Pepperonis. If it is known that none of the customers purchased more than one pizza of a particular type, and each customer purchased at least one pizza, then select for Minimum number of customers the least possible customers the shop could have received and for Maximum number of customers the maximum possible customers the shop could have received. Make only two selections, one for each.

I don’t quite agree with the solution. Surely the absolute minimum number of customers would be 2. The question never states that a customer can only purchase 1 pizza only 1 type of pizza i.e. margarita or pepperoni. Thus, you could have 1 customer by all the margaritas and another buy all the pepperoni.

You should read the question more carefully. It explicitly states that no customer purchased more than one pizza of a particular type, which means a customer can buy at most one Margarita and one Pepperoni. Therefore, a single customer cannot buy all 70 Margaritas or all 100 Pepperonis, and having only 2 customers is not possible.

By the way, this doubt has already been addressed in the thread, so please read the topic carefully as well.
