Solution
The correct option is A 375 It is given that there are 15 students in each row of the assembly and there are a total of 25 rows.
So, in order to calculate the total number of students, we need to multiply 15 with 25. 15 can be split into 10 + 5 and 20 can be split into 20 + 5. Now, by box method, we can calculate the answer.
