Option 1: C and D
Option 2: D and E
Option 3: B and C

Correct Answer: C and D
Solution :
Total number of employees in 1998 = 48,640
Percentage of A-type employees = 22%
Number of A-type employees in the year 1998 = $\frac{48640 \times 22}{100}$ ≈ 10,700
In the year 1997 the percentage of C and D type employees = 10+15 = 25%
Total number of employees in 1997 = 42,980
Number of C and D-type employees in the year 1997 = $\frac{42980 \times 25}{100}$ = 10,745
Hence, the correct answer is C and D.
