Correct Answer: B. capital account

Correct Answer: D) an oxime

Explanation

A ketone is an organic compound containing a carbonyl group (C=O) bonded to two alkyl groups. When a ketone reacts with hydroxylamine (NH₂OH), it forms a compound called an oxime.

Here is the general reaction for a ketone (R₁CO-R₂) reacting with hydroxylamine:

\(R_1CO-R_2 + NH_2OH \rightarrow R_1C(NOH)-R_2 + H_2O\)

In this reaction, the carbonyl group (C=O) of the ketone reacts with the hydroxylamine to form a new compound with a C=N-OH group, which is the characteristic functional group of an oxime. The other products of the reaction are water (H₂O).

Therefore, the correct answer isOption D: an oxime.

Some other options mentioned are not formed during this reaction:

• Hydrazone - formed when a ketone reacts with a hydrazine (NH₂-NH₂).
• Alkanonitrile - contains a cyano group (C?N) and is not formed by the reaction of a ketone with hydroxylamine.
• Nitroso compound - contains a nitroso group (N=O) and is not formed by the reaction of a ketone with hydroxylamine.

Correct Answer: A. Disc plough is used to create wider ridges on the field than disc Harrow

Explanation

Disc plough is used to create wider ridges on the field than disc harrow, because its disc are notched and about 54 discs can be used together at once, and also it is first used before disc harrow.

Explanation

\(\sum fx = 15 + 4x - 4 + 5x + 54 + 28 + 8 = 101 + 9x\)

\(\sum f = 5 + x - 1 + x + 9 + 4 + 1 = 18 + 2x\)

\(\bar{x} = \frac{\sum fx}{\sum f}\)

\(5 = \frac{101 + 9x}{18 + 2x} \implies 101 + 9x = 5(18 + 2x)\)

\(101 + 9x = 90 + 10x \implies 101 - 90 = 10x - 9x\)

\(11 = x \)

(b)(i) Mode = 5.

(ii) Median

Frequency = 18 + 2(11) = 40.

Median position = \(\frac{40}{2} = 20\)

20th position = 5.

(c) No of students that scored at least 7 marks = 4 + 1 = 5.

Probability of scoring at least 7 marks = \(\frac{5}{40} = \frac{1}{8}\)

Correct Answer: C. 2.0

Explanation

The required answers should include:

i. The statement of the central theme.

ii. The location of the shrine.

iii. The role of the shrine.

iv. The desecration of the shrine.

v. The consequences of the desecration.

Explanation

(a) Maximum price legislation is a policy of fixing the price of a product below its equilibrium price by the government, above which it is illegal to sell the product.

(b)(i) To enhance stability of farmers’ incomes in times of bumper harvest.

(ii) To encourage a steady flow of agricultural output at stable prices.

(iii) To stabilize the amount of incomes households spend on food, making it possible for households to plan their expenditure on

(iv) To prevent exploitation of farmers by middlemen who may want to pay lower prices for their produce.

(v) To reduce the risks associated with price fluctuations of agricultural produce.

(c)(i) Fixing price below equilibrium may lead to excess demand. This creates shortage of the product.

(ii) Parallel/illegal/black markets may develop and some products may disappear from the regular markets to be sold in illegal markets at prices far above the equilibrium price.

(iii) Shortage of products may lead to rationing. This may place a limit on the quantity of products consumers can buy.

(iv) Conditional sales will emerge where buyers may be required to fulfill certain conditions before purchases can be made.

(v) Queues will develop since the commodities are hard to come by.

(vi) Distortions in production may result as only products whose prices are not controlled will be produced.

(vii) Preferential sales will emerge as sellers will sell to whom they know.

(viii) Hoarding of goods will become prevalent.

(ix) Goods will be smuggled to areas/places with higher prices.

(x) Loss of profit for producers will lead to a reduction in the quality of the products.
