The students in a class are made to stand in rows. If 3 students are extra in a row, there would be 1 row less. If 5 students are less in the row, there would be 3 rows more. Find the number of students in the class. ?

Correct

Answer: 5) 90
Explanation:
Let no. of students in each row = x
And no. of row = y
Then no. of students will be x.y
Case 1
Students in row = x+3
No. of rows = y-1
Xy = (x+3).(y-1)
Xy=xy-x+3y-3
x-3y+3 = 0……………………………………………………….(1)
Case 2
Students in row = (x-5)
No. of rows = (y+3)
Xy = (x-5).(y+3)
Xy = xy+3x-5y-15
5y-3x+15 = 0 ……………………………..(2)
Solving (1) and (2) we get , x = 15 and y =6
Total students = 15 × 6 = 90
