  • d) 45
  • a) 55
  • b) 54
  • c) 46
  • d) 45

correct answer : b)

Explanation:

Total tires sold = 1350.
From the pie chart:
• Avon = 21% of 1350 = 0.21 × 1350 = 283.5
• Firestone = 14% of 1350 = 0.14 × 1350 = 189
• Good year = 12% of 1350 = 0.12 × 1350 = 162
• Dunlop = 15% of 1350 = 0.15 × 1350 = 202.5

Average of Avon and Firestone = (283.5 + 189) ÷ 2 = 472.5 ÷ 2 = 236.25
Average of Good year and Dunlop = (162 + 202.5) ÷ 2 = 364.5 ÷ 2 = 182.25

Difference = 236.25 − 182.25 = 54

बेचे गए कुल टायर = 1350.
पाई चार्ट से:
• Avon = 1350 का 21% = 0.21 × 1350 = 283.5
• Firestone = 1350 का 14% = 0.14 × 1350 = 189
• Good year = 1350 का 12% = 0.12 × 1350 = 162
• Dunlop = 1350 का 15% = 0.15 × 1350 = 202.5

Avon और Firestone का औसत = (283.5 + 189) ÷ 2 = 472.5 ÷ 2 = 236.25
Good year और Dunlop का औसत = (162 + 202.5) ÷ 2 = 364.5 ÷ 2 = 182.25

अंतर = 236.25 − 182.25 = 54
