Detailed Solution
Download Solution PDFGiven :
B buys 10 pens for ₹8 each.
10 erasers for ₹5 each.
Some sharpeners for ₹4 each.
Formula Used :
Average = Sum of all observations/Number of observations
Calculation :
⇒ 150 = 10 × 8 + 10 × 5 + 4 × x
⇒ 150 = 80 + 50 + 4x
⇒ 4x = 20
⇒ x = 5
Average = 150/(5 + 10 + 10) = 150/25 = 30/5 = 6
∴ The correct answer is 6.
