What is the fraction (%) of employees getting salary ≥ 40,000 per month ?

Concept

To find what percentage of a group meets a condition, count the members satisfying the condition, divide by the total number of members, and multiply by 100. The comparison must use the stated threshold, including equality when the symbol is ≥.

Application

1. The salaries are listed in thousands of rupees, so a monthly salary of at least ₹40,000 corresponds to a table value of at least 40.

2. The qualifying salaries are 45, 60, 50, 55, 40, 45, 50, 45, and 50. Thus, 9 employees satisfy the condition.

3. There are 20 employees in total. Therefore, the required percentage is (9 ÷ 20) × 100 = 45%.

Cross-check

The remaining 11 employees have salaries below ₹40,000; 20 − 11 = 9. This independently confirms the count and hence the percentage.

Result

The fraction of employees earning at least ₹40,000 per month is 45%.
