The mean salary of a group of 50 persons is Rs. 5,850. Later on it is ...
Given information:
- Mean salary of a group of 50 persons = Rs. 5,850
- One employee's salary wrongly recorded as Rs. 8,000 instead of Rs. 7,800

To find: Corrected mean salary

Solution:
Step 1: Calculate the sum of salaries of all 50 persons
Total salary = 50 x 5,850 = Rs. 2,92,500

Step 2: Subtract the wrongly recorded salary (Rs. 8,000) and add the correct salary (Rs. 7,800)
Total salary = 2,92,500 - 8,000 + 7,800 = Rs. 2,92,300

Step 3: Calculate the corrected mean salary
Corrected mean salary = Total salary / Number of persons
Corrected mean salary = 2,92,300 / 50 = Rs. 5,846

Therefore, the corrected mean salary is Rs. 5,846, which is option (b).

Mean salary =5850 for 50 persons

salary =5850×50
