Solutions:
1. E) Number of students of MFC in Chennai = 1342
Number of students of MPM in Chennai = 1666
Required percentage = 1342/1666 x 100 = 80.55 = 81
2. E) Number of MBM students in Ahmedabad = 1289
Number of MCA students in Ahmedabad = 1440
Required percentage = 1289/1440 x 100 = 89.5 = 90
3. B) Total Number of MIB  students in all citites = 10104
Total Number of MFC students in all cities = 8844
Difference 10104 – 8844 = 1260
4. D) Total number of students :
Bengaluru – 1156 + 1783 + 1874 + 1003 + 1340 = 7156
Chennai – 1342 + 1473 + 1129 + 1765 + 1666 = 7375
New Delhi – 1230 + 1098 + 1128 + 1865 + 1777 = 7098
Hyderabad – 1456 + 1234 + 1556 + 1653 + 1789 = 7688
Kolkata – 1239 + 1785 + 1865 + 1504 + 1762 = 8155
The number of students was highest in Kolkata.
5. C) Number of students enrolled in MIB course = 1384 + 1783 + 1347 + 1473 + 1098 = 10104
Required average = 10104/7 = 1443
6. E) Total number of children who are in section B in all the classes together = 150+425+425+200+325 = 1525
7. C) Total number of students in Section A: 1775, Section B: 1525 and Section C: 1425
Therefore required ratio = 1775:1525:1425 = 71 : 61 : 57
8. E) Section B, class 3 = 425
Total in section B = 1525
So required % = 425/1525 * 100 = 28%
9. A) Section A, class 1 = 250
Total in class 1 = 250+150+200 = 600
So required % = 250/600 * 100 = 41.67%
10. A) Class 2 = 450+425+350 = 1225
Class 4 + 5 = 300+200+175 + 300+325+325 = 1625
So required % = (1625-1225)/1625 * 100 = 24.62%
