ANSWERS
1. (5)

2. (1)

3. (3) 1480/5 = 296

4. (5);
Number of hours by Grade C
= (300 + 322 + 317 + 300) × 8
= 9912

5. (2);
Total work = (310 + 312 + 315 + 330) × 8
= 1267 × 8
= 10136
Average = 10136/4 = 2534 hours


Solutions (6-10):

45 – x + 20 + 35 + 10 + x + 40 + 65 – x = 200
215 – x = 200
x - 215 – 200 = 15
