The correct answer is 1942.

Key Points

• The Cripps Mission came to India in 1942.
• The mission was led by Sir Stafford Cripps, a member of the British Cabinet. 
• It aimed to secure Indian cooperation and support for the British war efforts during World War II.
• The mission proposed Indian dominion status after the war, which was rejected by Indian leaders.
• The failure of the Cripps Mission led to the intensification of the Indian independence movement, including the Quit India Movement.

Additional Information

• The Cripps Mission was part of a series of attempts by the British government to secure Indian support during World War II.
• Despite its failure, it marked a significant moment in the Indian struggle for independence.
• The proposals included the establishment of an Indian Union with full Dominion status, which was to be created after the war.
• Provinces and princely states were given the option to opt-out of the Union, which was a contentious point for Indian leaders.

Given:

Principal (P) = 1,000

Rate (R) = 10%

Time (T) = 3 years

Formula Used:

1. Simple Interest (SI) = P × R × T / 100
2. Compound Interest (CI) = P × (1 + R/100)^T - P
3. Difference = CI - SI

Calculation:

Simple Interest:

SI = 1,000 × 10 × 3 / 100

⇒ SI = 300

Compound Interest:

CI = 1,000 × (1 + 10/100)³ - 1,000

CI = 1,000 × (1 + 0.1)³ - 1,000

CI = 1,000 × (1.1)³ - 1,000

CI = 1,000 × 1.331 - 1,000

CI = 1,331 - 1,000

⇒ CI = 331

Difference:

Difference = CI - SI

Difference = 331 - 300

⇒ Difference = 31

The difference in interest yielded in 10% compound rate and simple rate on a sum of 1,000 for 3 years is 31.

The correct answer is Tropical Evergreen.

Key Points

• The North-Eastern states of India are predominantly covered with Tropical Evergreen forests.
• Tropical Evergreen forests are characterized by high rainfall and a warm climate throughout the year. 
• These forests remain green all year round and are known for their dense canopy.
• Some key features of Tropical Evergreen forests include:
• High biodiversity.
• Multiple layers of vegetation, including tall trees, shrubs, and undergrowth.
• Presence of valuable timber species like mahogany, ebony, and rosewood.
• These forests play a crucial role in maintaining ecological balance and supporting diverse wildlife.

Additional Information

• Other types of forests in India include:
• Tropical Deciduous forests: Found in regions with seasonal rainfall, these forests shed their leaves in the dry season.
• Coastal forests: Found along the coastal regions, these include mangroves and other salt-tolerant species.
• Tropical Desert forests: Found in arid regions with sparse vegetation, mainly consisting of thorny bushes and cacti.

The correct answer is Frequency.

Key Points

• Hertz (Hz) is a unit of frequency.
• Frequency refers to the number of cycles per second of a periodic wave.
• One Hertz is equivalent to one cycle per second.
• It is used to measure phenomena such as sound waves, radio waves, and electrical signals.

Additional Information

• Density is a measure of mass per unit volume.
• Wavelength is the distance between successive crests of a wave.
• Energy is the capacity to do work or produce heat.

The correct answer is Antimony.

Key Points

• Antimony is a chemical element with the symbol Sb and atomic number 51.
• Unlike most substances, antimony expands upon cooling. This is a key characteristic that sets it apart from other elements.
• When antimony solidifies from its liquid state, its volume decreases, which is contrary to the behavior of most other metals.

Additional Information

• Most substances expand when they transition from a liquid to a solid state due to the decrease in density.
• For example, ice, the solid form of water, occupies more volume than liquid water, which is why ice floats.
• Similarly, metals like aluminum and bismuth also expand upon solidification, increasing their volume.

Preparing the family tree using the following symbols,

Let's check each option,

1) W × R × F

2) W + R - F + T 

3) W ÷ R × F

4) W + R × F - T

 ⇒ Here, F is daughter of W.

Hence, the correct answer is "W + R × F - T".

The correct answer is Flagellar.

Key Points

• Locomotion of Euglena is done by flagellar.
• Flagella are long, whip-like structures that act as a propeller to move the organism.
• Euglena uses its flagellum to move through water.
• The flagellum is attached at the anterior end of the organism, and it rotates to propel Euglena forward.

Additional Information

• Cilia are short, hair-like structures that can move fluid or cells over their surface. They are not used by Euglena for locomotion.
• Pseudopodia are temporary projections of eukaryotic cell membranes or unicellular protists. They are used by amoebae for locomotion and feeding, not by Euglena.
• Fins are typically associated with aquatic animals like fish and are not relevant to Euglena.

Given:

Total sum = ₹ 2000

Interest from first part = 10%

Interest from second part = 20%

Total interest received = ₹ 320

Formula Used:

Total Interest = Interest from first part + Interest from second part

Calculation:

Let the first part be ₹ x.

Then the second part = ₹ (2000 - x).

Interest from first part = x × 10% = 0.1x

Interest from second part = (2000 - x) × 20% = 0.2(2000 - x)

Total Interest = 0.1x + 0.2(2000 - x)

Total Interest = 0.1x + 400 - 0.2x

Total Interest = 400 - 0.1x

Given Total Interest = ₹ 320

⇒ 400 - 0.1x = 320

⇒ 0.1x = 80

⇒ x = 800

The first part of the sum is ₹ 800.

The least possible venn diagram is shown below,

Conclusions:

I. Some trucks are pens → True (All pens are chairs, and all chairs are trucks implies that some trucks are pens).

II. Some trucks are chairs → True (All chairs are trucks implies that some trucks are definitely chairs).

III. Some trees are pens → False (All pens are chairs, all chairs are trucks and all trees are trucks implies that some trees can be pens. This is possible but not definite).

IV. Some trees are chairs → False (All chairs are trucks and all trees are trucks implies that some trees can be chairs. This is possible but not definite).

Hence, the correct answer is "Only I and II follow".

The correct answer is Judicial System.

Key Points

• The Ilbert Bill was introduced in 1883 during the tenure of Viceroy Lord Ripon.
• The bill was aimed at allowing Indian judges to preside over cases involving British citizens in India.
• It was a significant step towards judicial equality and was part of the broader reforms under Lord Ripon's administration.
• The bill faced strong opposition from the British community in India, leading to its modification.

Additional Information

• The opposition to the Ilbert Bill highlighted the racial tensions and the colonial mindset prevalent during British rule in India.
• The controversy eventually led to the bill being passed in a diluted form, allowing Indian judges to try European British subjects only in the presence of a jury with at least half of its members being Europeans.
