1
The average production of steel is:
Discuss
Answer & Solution
The average production during (1920 - 1927)
$$\frac{71.30 + 43.51 + 67.66 + 76.23 + 77.23 + 88.93 + 91.75 + 100.17}{8}$$
= 77.0975 million tons
≈ 77.10 million tons

The difference of the production of steel in the year 1923 and 1924 is x% of 1927. Then the value of x approximately.
Discuss
Answer & Solution
$$\eqalign{ & \text{According to the question,} \cr & \Rightarrow 100.17 \times \frac{x}{100} = \left(77.23 - 76.23 \right) \cr & \Rightarrow x = \frac{100}{100.17} \cr & \Rightarrow x = 0.99860..\% \cr & \Rightarrow x = 1\%\, \left(\text{Approx} \right) \cr} $$
3
The ratio of production of steel in the year 1924 and 1925 to that of 1923 and 1927 is:
Discuss
Answer & Solution
$$\eqalign{ & \text{Required ratio} \cr & = \frac{\text{Production of steel in }1924 + 1925}{\text{Production of steel in }1923 + 1927} \cr & = \frac{77.23 + 88.93}{76.23 + 100.17} \cr & = \frac{166.16}{176.4} \cr & = \frac{2077}{2205} \cr & = 2077 : 2205 \cr} $$
4
The number of years during which the company has its production less than the average production during 1920 - 1927 is approximately.
Discuss
Answer & Solution
The average production during (1920 - 1927)
$$\frac{71.30 + 43.51 + 67.66 + 76.23 + 77.23 + 88.93 + 91.75 + 100.17}{8}$$
= 77.0975 (million tons)
The required number of year
= 4 (1920, 1921, 1922, 1923)
