Explanation:
Step 1: Total employees for each year:
Total employees 2005 = 6,500
Total employees 2007 = 6,500
Step 2 Part-time employees for each year

Part-time employees for 2007 = 6,500 x 8% = 520
Step 3 Managers =
2005= 780 / 15 = 52
2007= 520 / 13 = 40
Step 4 Difference = 52 – 40 = 12
Thus the correct answer is (B) 12 more
