Hi


In this question, a student should note that the number of apples and oranges remains the same in both scenarios.

A student who is familiar with SE could proceed to use it. If not, he/she could solve it using the alphabet method or pictorially.

In this illustration, I’ve done it pictorially. As usual, I’ve put in more details than necessary because I wanted to show the flow of events. Once you understand the concept, you may express the solution in your own way.

Best wishes.
