1
Find the difference between the number of students of Electrical engineering of IIT Delhi to that of IIT Bombay. 
» Explain it
C
Total number of students in Electrical engineering in IIT Delhi

32  ×  17  × 1080 = 1088
27 20

Total number of students in Electrical engineering in IIT Bombay
19  ×  11  × 1420 = 1349
22 10

Required difference = 1349 – 1088 = 261

Hence, option C is correct.
2
35% and 20% of total students of Civil engineering of IIT Kharagpur are studying in 1st year and in 2nd year respectively while the ratio of number of students studying in 1st year, 2nd year, 3rd year, and 4th year in Civil Engineering in IIT Kanpur is 7:9:8:7 respectively. The total number of students studying in 1st year and in 2nd year together in Civil in IIT Kanpur is approximately what percent of the total number of students studying in 1st year and in 2nd year together in Civil in IIT Kharagpur?  
» Explain it
B
Total number of students studying in 1st year in Civil in IIT Kharagpur

= 35% of  36  × 1640 = 504
41

Total number of students studying in 2nd year in Civil in IIT Kharagpur
= 20% of  36  × 1640 = 288
41

Total number of students studying in 1st year in Civil in IIT Kanpur
7  ×  31  × 1260 = 315
31 28

Total number of students studying in 2nd year in Civil in IIT Kanpur
9  ×  31  × 1260 = 405
31 28

Reqd. % =  315 + 405  × 100 ≈ 91%
504 + 288

Hence, option B is correct.
3
If the ratio of the number of students in Electronics to Mechanical in IIT Bombay and IIT Kanpur is 4:5 and 71:70 respectively, then find the ratio of the number of students in Electronics in IIT Bombay to that in IIT Kanpur.  
» Explain it
A
Total number of students in Electronics in IIT Bombay

4  × 1420 = 1136
5

Total number of students in Electronics in IIT Kanpur
71  × 1260 = 1278
70

Required ratio = 8 : 9

Hence, option A is correct.
4
The total number of students of Civil Engineering of all the given colleges is approximately what percent of the total number of students of Mechanical Engineering of all the given colleges?
» Explain it
B
Number of students in civil in IIT Delhi

17  × 1080 = 918
20

Number of students in civil in IIT Bombay
11  × 1420 = 1562
10

Number of students in civil in IIT Kharagpur
36  × 1640 = 1440
41

Number of students in civil in IIT Kanpur
31  × 1260 = 1395
28

Number of students in civil in IIT Madras
13  × 1584 = 1287
16

Total number of students in civil in all five colleges = 918 + 1562 + 1440 + 1395 + 1287 = 6602

Total number of students in Mechanical in all five colleges = 1080 + 1420 + 1640 + 1260 + 1584 = 6984
 
Reqd. % =  6602  × 100 ≈ 95%
6984

Hence, option B is correct.
5
The total number of students in Computer Science in IIT Kharagpur, IIT Kanpur, and IIT Madras together is 286 more than the total number of students in Electrical in the same colleges together. Find the total number of students in Computer Science in IIT Kharagpur, IIT Kanpur, and IIT Madras together.   
» Explain it
D
Total number of students in Electrical in IIT Kharagpur

36  ×  23  × 1640 = 1840
41 18

Total number of students in Electrical in IIT Kanpur
31  ×  49  × 1260 = 1519
28 45

Total number of students in Electrical in IIT Madras
13  ×  34  × 1570 = 1122
16 39

Total number students in Computer Science in IIT Kharagpur, IIT Kanpur, and IIT Madras together

= 1840 + 1519 + 1122 + 286 = 4767

Hence, option D is correct.
