Give the step-by-step reasoning process and then the final answer. In Grade 4, there are two sections -- Diligence and Industry. The two sections have an equal number of students after 2 students were transferred from section Industry to Diligence. How many students were there in section Diligence before the transfer if, in both sections combined, there are a total of 50 students?
There are 50 / 2 = 25 students in each section now. So, there were 25 - 2 = 23 students in section Diligence before 2 students were transferred in their section.
The final answer: 23.
