How many per cent of employees get salaries less than Rs 30,000? The following data shows the salaries of all the employees of a company. Salary (In Rs.) 0-10,000 10,001-20,000 20,001-30,000 30,001-40,000 40,001-50,000 Number of Employees 235 105 50 40 20 Correct Answer 0.867

Calculation

No of employees whose salary lies from 0 - 19,000 = 235

No of employees whose salary lies from 10,001 - 20,000 = 105

No of employees whose salary lies from 20,001 - 30,000 = 50

Total employs whose salary lies from 0 - 30,000 = 235 + 105 + 50

⇒ 390

Total number of employs = 450

⇒ 390/450 = 0.867

∴ 86.7% employees get salaries less than Rs 30,000
