Correct Answer: I and II
Solution :
I. Production by company L in year Y1 = 60
Production by company M in year Y1 = 25
Required percentage = $\frac{60}{25}\times100 = 240 \%$
Given percentage = $24\%$
Thus, this statement is false
II. Ratio of production by company L in Y4 : M in Y4 = 15 : 50
= 3 : 10 and the given ratio is 10 : 3.
Thus, this statement is false.
III. Average production by L in Y2 and Y3 = $\frac{40+20}{2}=30$
Given average is 30.
Thus, this statement is true.
Hence, the correct answer is I and II.
