Correct Answer: Neither I nor II
Solution : Given, Total = 10000 Statement I: The average number of cars sold by companies B, F, and H is 100. Number of cars sold by B = 8% of 10,000 = 800 Number of cars sold by F = 12% of 10,000 = 1200 Number of cars sold by H = 10% of 10,000 = 1000 $\therefore$ Average = $\frac{800+1200+1000}{3}=\frac{3000}{3}=1000$ ⇒ Statement I is incorrect. Statement II. The ratio of the number of cars sold by A to the number of cars sold by E is 4 : 5. Number of cars sold by A = 20% of 10,000 = 2000 Number of cars sold by E = 16% of 10,000 = 1600 $\therefore$ Ratio = 2000 : 1600 = 5 : 4 ⇒ Statement II is incorrect. Hence, the correct answer is Neither I nor II.
