If the ratio of the domestic sale price of a commercial vehicle, a passenger vehicle, and a three wheeler is 5:3:2 then what percent of earnings (approximately) is contributed by commercial vehicle segment to the overall earnings from domestic sales during the period 2004-2008?
Explanation:
Total domestic sale for the year 2004-2008:
Commercial vehicles: 450 + 500 + 625 + 600 + 550 = 2725
Passenger vehicles: 700 + 675 + 900 + 1050 + 975 = 4300
Three wheelers: 300 + 350 + 400 + 375 + 350 = 1775
∴ Ratio of the total sale price of commercial vehicles, passenger vehicles and three wheelers = (5 × 2725) : (3 × 4300) : (2 × 1775)
∴ Contribution of commercial vehicles to the overall earnings
= (5×2725)(5×2725)+(3×4300)+(2×1775) × 100 ≈ 45%
Hence, option (a).
