Question:
The average score of 7 players was initially recorded as 55. However, it was later discovered that a score of 35 had been mistakenly read as 53. Determine the correct average score (rounded up to two decimal places).
7 खिलाड़ियों का औसत स्कोर प्रारंभ में 55 दर्ज किया गया था। बाद में पता चला कि 35 के स्कोर को गलती से 53 पढ़ लिया गया था। सही औसत स्कोर ज्ञात कीजिए।
Options:
- 54.31
- 32.43
- 52.43
- 42.08
- 54.31
- 32.43
- 52.43
- 42.08
Correct Answer: (c)
Explanation:
Detailed Explanation: Total initial score = 7 × 55 = 385. Error correction = 35 – 53 = -18. Correct total = 385 – 18 = 367. Correct average = 367 / 7 = 52.428… ≈ 52.43.
विस्तृत व्याख्या: कुल स्कोर = 7 × 55 = 385। त्रुटि सुधार = 35 – 53 = -18। सही कुल योग = 385 – 18 = 367। सही औसत = 367 / 7 = 52.43।
