Answer :

1. 2; 
Total number of students studying in all the colleges in 2012
= (1125 + 330 + 290 + 1050 + 450 + 325 + 1200 + 420 + 400 + 1600 + 440 + 400+ 1550 + 350 + 380) - (220 + 2 10 + 250 + 215 + 230 + 250 +260 + 225 + 230) = 7970
∴ Required average = 7970/5 = 1594

2. 4; 
Required number of students
= 1050 + (450-250) +  (325-215) + (285 - 210) + (300-190)
= 1545

3. 3;
Required percentage = 1225/3130 x 100 = 39%

4. 1;
Required difference
= (440 + 400 + 395 + 420 + 460) - (450 + 325 + 285 + 300 + 340)
= 2115 - 1700 = 415

5. 5;
Increase in the number of students in college A
= (330 - 220) + (290 - 210) + (345 - 200) + (380 - 250) + (350 - 230)
= 585
