कुटुंबातील 6 सदस्यांचे सरासरी वय 25 वर्षे आहे.
कुटुंबातील सर्वात लहान सदस्याचे वय 8 वर्षे आहे.
वापरलेले सूत्र:
सरासरी = (एकूण निरीक्षणांची बेरीज)/(निरीक्षणांची एकूण संख्या)
गणना:
सरासरी = (एकूण निरीक्षणांची बेरीज)/(निरीक्षणांची एकूण संख्या)
⇒ (एकूण निरीक्षणांची बेरीज) = सरासरी × (निरीक्षणांची एकूण संख्या)
कुटुंबाची एकूण बेरीज = 6 × 25 = 150 वर्षे
मुलाचे वय 8 वर्षे आहे, त्याच्या जन्मापूर्वी कुटुंबातील सर्व 5 सदस्य सध्याच्या वयापेक्षा 8 वर्षे कमी आहेत
म्हणून, कुटुंबाच्या वयाची नवीन बेरीज = 150 – 8 × 6 = 102 वर्षे
आवश्यक सरासरी = 102/5 = 20.4 वर्षे
∴ आवश्यक सरासरी 20.4 वर्षे आहे.
