Correct Answer: Only I
Solution :
I. Total production of trucks by all 5 companies = 700 + 500 + 400 + 800 + 850 = 3250 units
Total production of bikes by all 5 companies = 900 + 650 + 700 + 450 + 500 = 3200 units
Required percentage = $\frac{\text{Total production of trucks by all 5 companies}}{\text{Total production of bikes by all 5 companies}}\times 100$
= $\frac{3250}{3200}\times 100 = 101.56$%
Given percentage is 201.50%
Thus, the statement is NOT correct.
II. Production of bikes by R = 900
Production of trucks by R = 700
Average production = $\frac{\text{Production of (Bikes + Truck)}}{2}=\frac{900+700}{2}=800$
Given average is 800.
Thus, this statement is correct.
Hence, the correct answer is Only I.
