Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e W and X.
The number of workers doing U-type of work in 2006 = 22%
⇒ 22% × 54000 = 11880
The number of workers doing W-type of work in 2005 = 10%
⇒ 10% × 47520 = 4752
The number of workers doing X-type of work in 2005 = 15%
⇒ 15% × 47520 = 7128
Total workers in W and X = 4750 + 7128 = 11880
11880 is equal to the number of workers doing U-type of work in 2006
