To Find : number of rooms required in a day for examination.
Solution:
Three classes have 35,49 and 42 students respectively.
first need to find HCF to find maximum number of students in a room
35 = 5 x 7
49 = 7 x 7
42 = 2 x 3 x 7
7 is the only common factor in all 3
Hence number of students in a room = 7
Total students = 35 + 49 + 42 = 126
number of rooms required in a day for examination. = 126/7
= 18
18 rooms required
