The average salary of employees in a company is ₹20,000. If a new employee with a salary of ₹50,000 joins, the average increases by ₹500. Find the number of employees originally in the company.
59
55
60
65
Answer: A
Let the original number be n. Then (20000n+50000)/(n+1)=20500. Solving gives 20000n+50000=20500n+20500, so n=59.
एक कंपनी में कर्मचारियों का औसत वेतन ₹20,000 है। ₹50,000 वेतन वाला नया कर्मचारी शामिल होने पर औसत ₹500 बढ़ जाता है। कंपनी में मूल रूप से कितने कर्मचारी थे?
59

65
उत्तर: A
माना मूल कर्मचारियों की संख्या n है। तब (20000n+50000)/(n+1)=20500। हल करने पर 500n=29500, इसलिए n=59।
