Correct Answer: 20.4%
Solution :
The number of workers who earn between Rs. 950 to Rs. 960 = 10
The total number of workers surveyed = 3 + 2 + 4 + 9 + 5 + 10 + 5 + 3 + 3 + 5 = 49
$\therefore$ The required percentage
= $\frac{\text{The number of workers who earn between Rs.950 to Rs.960}}{\text{The total number of workers surveyed}}\times 100$
= $\frac{10}{49}\times 100$
= $20.4\%$
Hence, the correct answer is 20.4%.
