Concept-

• Crops are plants or plant-derived products that are produced and harvested for food or profit.
• Food crops, feed crops, fibre crops, oil crops, ornamental crops, and industrial crops are the six main types of crops.

Key Points Rabi crops-

• Rabi crops, also known as rabi harvest, are Indian agricultural crops that are planted in the winter and harvested in the spring.
• Rabi crops are planted in mid-November, ideally, after the monsoon rains have passed, and harvested in April/May.
• Rainwater that has percolated into the ground or irrigation are used to cultivate the crops. Winter rains wreak havoc on rabi crops.
• Wheat is India's most important rabi crop, followed by barley, mustard, sesame, and peas. Peas are picked early because they are ripe early: from January through March, Indian markets are swamped with green peas, with February being the peak month.

Additional Information Kharif crops-

• Kharif crops also known as monsoon crops or autumn crops are domesticated plants grown and harvested in India, during the monsoon season, which lasts from June to November depending on the region.
• In some parts of the Indian subcontinent, monsoon rains can start as early as May, and crops are harvested between the third and fourth weeks of September and October.
• Rice, maize, and cotton are among India's most important Kharif crops.

The correct answer is Ravina asked her little brother where he was going to play​.

Key Points​

• Let's look at the steps to change the sentence from direct to indirect speech:
• The tense of direct speech is changed only when the reporting verb is in the past tense.
• When the direct speech is in an interrogative form, we follow the steps given below:
• The reporting verb asked will remain the same.
• The word 'where will follow the removal of comma and inverted commas.
• Change the reported speech from interrogative to assertive.
• Present continuous tense (are you going) in direct speech changes to past continuous in indirect speech (he was going).
• ​The personal pronouns will be changed according to the subject and object of the reporting verb.
• Here 'you' will be converted into 'he' as per the subject.
• ​​At last line up the remaining part.

Following these steps, we finally get - Ravina asked her little brother where he was going to play.

Shortcut Trick

Solve the expression by simplifying from the innermost square root moving outwards.

First part: √(6 + 3) = √9 = 3

Second part: √(19 − 3) = √16 = 4

Final part: √(21 + 4) = √25 = 5

∴ The correct answer is 5.

Alternate Method

Given: √(21 + √(19 − √(6 + 3)))

Following the BODMAS rule, we evaluate the operations inside the radical signs sequentially:

⇒ √(21 + √(19 − √9))

⇒ √(21 + √(19 − 3))

⇒ √(21 + √16)

⇒ √(21 + 4)

⇒ √25

⇒ 5

∴ The correct answer is 5.

Additional Information

Perfect Squares

A perfect square is an integer that is the square of another integer. Common examples include 3² = 9, 4² = 16, and 5² = 25.

VBODMAS Rule

In nested mathematical operations, Vinculum (Bar), Brackets, and operations inside Orders (Roots/Powers) are prioritized from the innermost level to the outermost level.

Surds Property

While √(a × b) = √a × √b, it is important to remember that √(a + b) ≠ √a + √b.

The correct answer is D.

Additional Information

The correct answer is 'RQPS.'

Key Points

• While arranging the parts of the sentence given in options, we have to find some grammatical or contextual connections between them, so let’s find out.
• In this sentence, we can see that there are different parts like Subject, indirect object, subject of subordinating clause and verb, indirect object, and direct object.
• The sentence must start with R as it is providing an introduction to the context "belief of peoples in several cultures".
• R must be followed by Q as it is expressing what people believe i.e. shooting stars have some power.
• Q must be followed by P as it talks about what the power of shooting stars is believed to be i.e. to make wishes true.
• S must be the last part as it is providing a conclusion to the sentence.

​​Correct sentence: In several cultures, people believe that shooting stars have the power to make wishes come true and become successful in life.

Additional Information         

• Before rearranging parts of the sentence, it is very important to read them carefully.
• It is very important to analyse the use of a determiner and conjunction in such cases.
• This confusion can be eradicated by practising more and more questions of Sentence Jumbles.

Shortcut Trick

Total members = 78 + 22 + 34 = 134

⇒ Ratio = 78:22:34 = 39:11:17

⇒ Weighted avg = (39×136 + 11×383 + 17×457) ÷ 67

⇒ = (5304 + 4213 + 7769) ÷ 67 = 17286 ÷ 67 = 258

∴ Answer = 258

Alternate Method

Given:

A: 78 members, avg = 136

B: 22 members, avg = 383

C: 34 members, avg = 457

Formula:

Overall avg = (Σ (n × avg)) ÷ Σ n

Calculations:

⇒ Total amount A = 78 × 136 = 10608

⇒ Total amount B = 22 × 383 = 8426

⇒ Total amount C = 34 × 457 = 15538

⇒ Total amount = 10608 + 8426 + 15538 = 34572

⇒ Total members = 134

⇒ Average = 34572 ÷ 134 = 258

Final Answer: 258

Additional Information

Weighted Average: (Σ n_ix_i) ÷ Σ n_i

Ratio Trick: Simplify group sizes before calculation

Concept: Larger group dominates overall average

Exam Tip: Use reduced ratio to save time

• The launching of a rocket illustrates Newton’s third law of motion.
• Newton's Third Law of Motion states that 'To every action, there is an equal and opposite reaction'.
• When the rocket is ignited, it releases gases from its thrusters thereby creating a force that will push rocket upwards.
• A fielder pulling his hand back while catching a ball is an application of Newton's second law of motion.
• Newton's Second Law of motion states that the rate of change of momentum of an object is proportional to the applied force in the direction of the force. i.e. F=ma. Where F is the force applied, m is the mass of the body, and a is the acceleration produced.
• When a bus starts suddenly, the passengers receive a backward jerk an application of Newton's first law of motion.
• Newton First law states that Every object remains in uniform motion in a straight line unless compelled to change its state by the action of an external force.
• When we stop pedalling, the bicycle slows down due to the frictional force acting on the bicycle.
