Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
B प्रत्येकी ₹8 ला 10 पेन खरेदी करतो.
प्रत्येकी ₹5 साठी 10 इरेजर.
काही शार्पनर प्रत्येकी ₹4 ला.
वापरलेले सूत्र:
सरासरी = सर्व निरीक्षणांची बेरीज/निरीक्षणांची संख्या
गणना:
⇒ 150 = 10 x 8 + 10 x 5 + 4 xx
⇒ 150 = 80 + 50 + 4x
⇒ 4x = 20
⇒ x = 5
सरासरी = 150/(5 + 10 + 10) = 150/25 = 30/5 = 6
∴ योग्य उत्तर 6 आहे.
