31. Consider the following statements regarding weightage of different articles in Wholesale Price Index (WPI).

1. Fuel and power have higher weightage in WPI than that of primary articles.
2. Weightage of manufactured products in WPI is higher than that of fuel and power.

Which of the statements given above is/are correct?

Correct Answer: (b) Only 2
Solution:Fuel and power have lower weightage in WPI than primary articles, which include essential items like food and minerals. In contrast, manufactured products carry a higher weightage in WPI due to their diverse range and significant impact on overall inflation.

32. If India enters into Free Trade Agreements (FTAs) with other nations, then the growth of exports of India would depend upon which of the following?

1. Extent of tariff reduction vis-a-vis MFN tariffs
2. Extent of relaxation in terms of rules of origin
3. Extent of relaxation in sanitary and phytosanitary measures
4. Level of infrastructure in India
5. Income in nations with which India enters into FTAs

Select the correct answer using the codes given below.

Correct Answer: (b) 1, 2 and 4
Solution:India's export growth under Free Trade Agreements (FTAs) would depend on several factors, but among the options listed, the most crucial ones are Extent of tariff reduction visa-a-visa MFN Tariffs, Extent of relaxation in terms of rules of origin and Level of infrastructure in India.

33. Which one of the following is an amphoteric oxide?

Correct Answer: (d) AL₂O₃
Solution:

34. The correct order of octane number of butane, pentane, hexane and cyclohexane is

Correct Answer: (d) cyclohexane > butane > pentane > hexane
Solution:Octane number of a fuel represent its efficiency. Higher the act one number better in fuel. As number of carbon atom in a alkane increases its octane number decrease cyclic hydrocarbon are better fuel than open chain hydrocarbon because they have high octane number. Therefore correct order is cyclohexane > butane > pentone > hexane Octane number of n octane in considered as zero while iron iso octane it is 100. If octane number is 80 it means it will create that much knocking as if we take 80% and 20% n octane mixture.

35. Which one of the following is the correct order of reactivity of Mg, Al, Zn and Fe with HCI?

Correct Answer: (a) Mg > AI > Zn > Fe
Solution:

36. Methanol is toxic because

Correct Answer: (c) methanol gets oxidised to acetic acid in liver which coagulates the protoplasm
Solution:Methanol is very toxic in nature. Methanol is oxidised into methanol from oxygen of our body. This methanol is reacts rapidly with the cells and it is responsible for the coagulation of protoplasm. Beside this methanol also affects the optic nerves. Damage of optic nerves causes blindness.

37. Vinegar is

Correct Answer: (a) 5-8% solution of acetic acid in water
Solution:Vinegar is 5-8% solution of acetic acid in water.

Commercially it is obtained by destructive distillation of used. After removing the gases, on condensation pyroligneous acid forms which contains vinegar, (5 to 8% acetic acid) methanol and propanone (0.5%) 2-4%. By removing methanol and propane by chemical method, we get vinegar.

38. Which one of the following is related to global dimming?

Correct Answer: (d) Fall of temperature due to increased particulates.
Solution:In global dimming, temperature is fall down due to increased particulate. These particulate particle increases due to increased particular. These particulate particle increases due to air pollution. Sulphate ion are major causes of global dimming.

39. Which one of the following is known as cetane?

Correct Answer: (a) Hexadecane
Solution:Hexadecane is named as cetane chemical formula of cetane is C¹⁶H³⁴. It is saturated hydrocarbon all carbon atoms are sp³ hybridized and bond angles are 109°28′. Efficiency of fuel (normally diesel) represent in cetane number citane Number CN = % by volume h hexadecane + % by volume a methyl nepthalene)

Higher the cetane number better in fuel.

40. Which one among the following countries is not part of the Arabian Peninsula?

Correct Answer: (c) Jordan
Solution:Jordan is not a part of Arabian Peninsula. The Arabian Peninsula consists 7 countries, i.e., Saudi Arabia, Yemen, Oman, UAE, Bahrain, Qatar and Kuwait.
