ANSWERS
1. (1)
Required Average = (3750 + 3000 + 2500 + 3750 + 3500)/5 = 3300

2. (2)
Total number of students (males and females together) in University P and R together = (3000 + 3750) + (2500 + 4250) = 13500

3. (2)
Required ratio = (3750 + 3000) : (4250 + 2750) = 27 : 28

4. (4)
Required percentage = 4000/(4000 + 3000) * 100  = 57% (approx)

5. (3)
Required number = 2750 + 50% of 2750 + 3500 = 7625

Solutions  (6-10)
6. (2)

7. (3)
Required ratio = (107 + 102) : (101 + 88) = 209 : 189

8. (2)
Required average = 592/6 = 99 (approx)

9. (4)
Required percentage = (94 - 84)/ 84 * 100 = 12 (approx)

10. (1)
Required percentage = 103/611 * 100 = 17
