Detailed Solution
Download Solution PDFदिया गया है:
B प्रत्येक ₹8 के हिसाब से 10 पेन खरीदता है।
₹5 प्रत्येक के लिए 10 रबड़ खरीदता है।
₹4 प्रत्येक के लिए कुछ कटर खरीदता है।
प्रयुक्त सूत्र:
औसत = सभी प्रेक्षणों का योग/प्रेक्षणों की संख्या
गणना:
⇒ 150 = 10 × 8 + 10 × 5 + 4 × x
⇒ 150 = 80 + 50 + 4x
⇒ 4x = 20
⇒ x = 5
औसत = 150/(5 + 10 + 10) = 150/25 = 30/5 = 6
∴ सही उत्तर 6 है।
