Answer:
Total no. of students = 275
No .of students absent on rainy day = 7/25×275
=11×7 = 77
No. of students present = 275-77 = 198
out of 198 students 7/11 part had brought umbrella
No. of students that had brought umbrella = 7/11 ×198
= 126
No. of students who had not got any umbrella = 198-126 = 72
So 72 students had no umbrella
