Refer to the following Tables (A) and (B) to answer these questions.
Question: 1
The ratio of the number of organic chemicals for which the production has fallen to the number of inorganic chemicals for which production has fallen is
Organic chemicals for which the production has fallen = Aniline Acetone Anhydride Phenol Inorganic chemicals for which the production has fallen = Bleaching Powder Alum. Chloride Phosphate Calcium carbonate Calcium carbide oxide So, the ratio = \(4:6\) = \(2:3\)
The correct option is (D): 1:1

Question: 2
Of all chemicals shown, the highest percentage increase in production has been exhibited for
First we have to see, for which quantities production has increased. Highest percentage increase in production = \(\frac{[\text{Production - Previous Production}]}{\text{Previous Production}}\) \(\%\; increase = \frac{72895 - 61615}{ 61615}\) \(\%\;increase = \frac{11280}{61615 }\times 100\) \(\%\; increase = 18.30\%\)
The correct option is (D): Sodium bicarbonate

Question: 3
The chemical, whose production in 2003-04 as a proportion of its total production for the two-year period was the lowest, is
Production in 2003 - 04 as a proportion of its total production for the two-year period: By observing from the tables, we get Titanium oxide : Production in \(2002 = 30422\) Production in \(2003 = 19624\) Proportion = \(\frac{19624}{(30422+19624)}\) Proportion = \(\frac{19624}{50046}\) Proportion = \(39.21\%\)
The correct option is (D): None of these

Question: 4
If productive volatility is defined as the percentage change in production, and it is known that any chemical whose productive volatility is greater than 5% is classified as highly volatile, then how many chemicals are not highly volatile (amongst organic chemicals)
Organic chemicals: Glycol = \(327387\times1.05\) < Production in 2003, so highly volatile Formaldehyde = \(140384\times1.05\)>Production in 2003, so not volatile Fatty Acids = \(99320\times1.05\)<Production in 2003, so highly volatile Aniline = decrease in production Acetone =decrease in production Acetic acid= \(208921\times1.05\) < Production in 2003, so highly volatile Anhydride = decrease in production Benzene= \(329000\times1.05\)<Production in 2003, so highly volatile Phenol = decrease in production So, total value is 5.
