Answer 2

Harry put 5 movies on each shelf.

Explanation:

The information provided is:

• On 4 different days, he bought 2 movies.
• On 2 other days, he bought 3 movies each day.
• After that he sold 2 sets of 2 movies.
• He divided the remaining into 2 groups to put onto his shelves.

So, first Harry bought 2 movies on four different days.

That is, a total of 8 movies.

Then, he bought 3 movies on two other days.

That is, a total of 6 movies.

So, in total Harry bought 14 movies.

Now, he sold 2 sets of 2 movies.

That is, he sold 4 movies.

He has 14 - 4 = 10 remaining movies with him.

It is provided that he divided remaining movies into 2 groups to put onto his shelves.

So, he put 10/2 = 5 movies on each shelf.
