How many employees get salaries less than Rs 30,000? The following data shows salaries of all the employees of a company:Salary Data of Employees in a Company
Salary (in Rs.) / वेतन (रुपये में) 0 - 10,000 10,001 - 20,000 20,001 - 30,000 30,001 - 40,000 40,001 - 50,000 Number of Employees / कर्मचारियों की संख्या 235 105 50 40 20
0.867
To find the fraction of employees earning less than Rs 30,000, we sum the employees in the salary ranges 0-10,000, 10,001-20,000, and 20,001-30,000. This gives 235 + 105 + 150 = 490 employees. The total number of employees is 400, so the fraction is 490/400 = 0.867. Hence, the correct answer is option 3, "0.867."
