ANSWERS WITH EXPLANATION:

1.     (4)
Number of students appeared in exam from college B in 2007 = (360*90)/100 = 324∴ Number of students passed = (324*75)/100 = 243

2.    (4)
Number of students appeared in exam from all colleges = 40% of (480+350+380+500+540)

= (40*2250)/100 = 900

3.    (3)
Reqd. ratio = (460+360+430+470+480) : (470+340+390+530+530)
=2200:2260=110:113

4.    (5)
∴Reqd. percentage = (334/402)*100 = 83.08% ≈ 83%

5.    (1)
Number of students in all colleges in 2006 = 420+300+410+520+460=2110

∴Number of students who went abroad = (2110*8)/100 = 168.8 ≈ 169

6.    (2)
Difference = 39500-33000=6500

7.    (5)
Percentage = (7500/39500)*100  ≈19%

8.    (1)
Ratio is 55:95= 11:19

9.    (3)
Percentage = (16000/23500)*100 ≈ 68%

10.  (1)
33000/5 = 6600
