The direct form of the given sentence is 'He said to her, "It is the most wonderful day of my life."

Key Points

• While changing a sentence from indirect speech to direct speech, we need to follow these steps-
  • The conjunction 'that' will be replaced with a comma (,) and inverted commas (" ").
  • 'Told' remains either unchanged or changed into 'said to'.
  • The simple past tense (was/were) is changed into the simple present tense (is/am/are).
  • The possessive adjective (his) is changed into 'my' i.e. according to the subject of the reporting verb (He).
  • 'That' is changed into 'it'.
    

The final sentence- He said to her, "It is the most wonderful day of my life."

The correct word is "convicts"

Key Points

• Let us take a look at the meanings of the given words :
  • convicts - to say officially in a court of law that somebody is guilty of a crime
  • defendants - a person who is accused of a crime in a court of law
  • prisoners - a person who is being kept in prison
  • jurors - a member of a jury
• The 11 people guilty of the rape against Bilkis Bano are mentioned here. therefore they are convicts.
• Thus, "convicts" will be the correct word here.

The correct sentence is : Chief Justice of India D. Y. Chandrachud on November 30 agreed to look into the listing of two petitions filed by Bilkis Bano, who was gangraped in the Gujarat riots, against the Gujarat Government's decision to prematurely release 11 convicts serving life sentence in her case. Making an oral mentioning before the CJI's Bench, advocate Shobha Gupta, for Ms. Bano, said her client has filed a review petition against a Supreme Court decision in May 2022.

The correct answer is 'forefathers'.
Key Points

• The term 'forefathers' is a synonym for 'ancestors' as it refers to people, especially one's relatives, that have lived in previous generations.
• Option A 'frontrunners', though possibly referring to people from an earlier era, typically denotes those who are first or leading in a competition or domain, not specifically ancestors.
• Option B refers to 'people living in our neighbourhood', but location doesn't directly relate to the concept of ancestry.
• 'Aboriginals', option D, refers to indigenous people, which doesn't necessarily mean they're the ancestors of the person referring to them.

Therefore, the correct answer is Option C, 'forefathers'.

The correct answer is 'By giving up the old habit of fighting to restore peace in life'.
Key Points

• The passage emphasizes true civilization should be characterized by peace and the rejection of conflict, indicating that giving up the habit of fighting is fundamental to being genuinely civilized.
• Options A and B don't align with the author's perspective, as they involve confrontation and wars - elements the author opposes in the description of a truly civilized society.
• Option C, despite promoting a peaceful sentiment, does not encompass all aspects of the author's thinking. Reducing armed forces doesn't necessarily guarantee giving up the "habit of fighting".

Therefore, the correct answer is Option D, 'By giving up the old habit of fighting to restore peace in life'.

Let’s break the given statement and solve it step-by-step:

1. His mother

2) ”His mother is the wife of my father’s only son.”

Hence, the correct answer is "Father".

According to the given information:

Anushka is twelfth from the right in a line of students and fourth from the left,

Total number of students in the line = Anushka's position from the right + Anushka's position from the left - 1 (because Anushka added two times)

Total number of students in the line ⇒ 12 + 4 - 1

⇒ 15

Now,

The number of students that should be added to line such that there are 28 students in the line = 28 - Total number of students in the line at present

= 28 - 15

= 13

Hence, the correct answer is "13".

The logic followed here is:

28 × 0.5 = 14

14 × 1 = 14

14 × 1.5 = 21

21 × 2 = 42

42 × 2.5 = 105

105 × 3 = 315

Hence, '315' is the correct answer.

Given:

The ratio of the speed of a boat in still water to the speed of the current is 11:4. The boat takes 72 minutes to travel 54 km downstream.

Concept:

Speed downstream (S_d) = Speed of boat in still water (B) + Speed of current (C)

Speed upstream (S_u) = Speed of boat in still water (B) - Speed of current (C)

Formula Used:

Time = Distance / Speed

Calculation:

We have,

⇒ B / C = 11 / 4

Let the speed of the boat in still water be 11x and the speed of the current be 4x.

⇒ S_d = 11x + 4x = 15x

⇒ Time to travel 54 km downstream = 72 minutes = 72/60 hours = 1.2 hours

⇒ 54 / (15x) = 1.2

⇒ 15x = 54 / 1.2

⇒ 15x = 45

⇒ x = 3

Speed of boat in still water (B) = 11x = 11 × 3 = 33 km/h

Speed of current (C) = 4x = 4 × 3 = 12 km/h

⇒ S_d = 33 + 12 = 45 km/h

⇒ S_u = 33 - 12 = 21 km/h

Time to travel 63 km downstream:

⇒ Time_d = 63 / 45 = 1.4 hours

Time to travel 42 km upstream:

⇒ Time_u = 42 / 21 = 2 hours

Total time:

⇒ Total Time = Time_d + Time_u

⇒ Total Time = 1.4 + 2 = 3.4 hours

∴ The boat will take 3.4 hours to travel 63 km downstream and 42 km upstream.

Given:

Pipe A and B can fill the tank in 32 h and 28 h

Concept used:

Total work = Efficiency of the pipes × time taken by the pipes

Calculation:

Let the total work be 224 units (LCM of 32, 28)

The efficiency of pipe A = 224/32 = 7 units/h

The efficiency of pipe B = 224/28 = 8 units/h

Now,

In 1st hour A completes 7 units

In the next 1 hour, B completes 8 units

So, in 2 hours 15 units are filled in the tank

In 28 hours, 15 × 14 = 210 units will be filled in the tank

The remaining 14 units,

Now A will work on 29^th hour,

210 + 7 = 217 units,

Now B will work and will complete the work,

⇒ 29 7/8

So, total time = 29 7/8hours

∴ The required answer is 30.

Shortcut TrickWe have,

,

Find two factors of 20 such that their difference is 1.

The larger factor will be the solution for expression.

Factors of 20 = 4 × 5

⇒ x2 - 20 = 5

∴ x = 5Alternate MethodConcept:

If y =

⇒ y =

Calculation:

We have

x² - 20 =

Using the above concept, (a = 20)

⇒ x² - 20 =

⇒ x2 - 20 =

⇒ x² = 25

∴ x = 5

Concept:

• The orthocenter is the point of intersection of altitudes.
• For an acute angle triangle, the orthocenter lies inside the triangle.
• For the obtuse angle triangle, the orthocenter lies outside the triangle.

Calculation:

The orthocenter is the point of intersection of altitudes

PL is perpendicular to QR

∴ QR is perpendicular to OP

NR is perpendicular to PQ

∴ PQ is perpendicular to OR

QM is perpendicular PR

The altitudes of POR are PN, RL and OM which intersect at Q

Since, Δ POR is an obtuse angle triangle, orthocenter will lie on

outside of triangle.

∴ Q is the orthocenter of POR.

Given:

The marked price of an item = ₹1,900.

The shopkeeper was offering a discount of 12%

After the 2nd discount, he sold the item for ₹1,538.24

Formula Used:

SP = (100 - D)/100 × MP

where, SP = Selling price, D = Discount offered, and MP = Marked price

Calculation:

Let the second discount be d%

At the first discount of 12%,

⇒ SP = (100 - 12)/100 × 1900

⇒ SP = 88/100 × 1900

⇒ 88 × 19 = 1672

Now, at the second discount of d%,

⇒ 1672 × (100 - d)/100 = 1538.24

⇒ 1672 × (100 - d)/100 = 153824

⇒ (100 - d) = 153824/1672

⇒ (100 - d) = 92

⇒ d = 100 - 92

⇒ d = 8%

Thus, the second discount offered by the shopkeeper is 8%.

Hence, the correct answer is 8%.

Given:
Marked Price = 15000
Three successive discounts of 5%, 10% and 20%.

Formula Used:

Selling Price = MP x 100-x/100 x 100-y/100 x 100-z/100

Where, MP is the marked price, x, y and z are successive discounts.

Calculation:

Selling Price = 15000 x 100-5/100 x 100-10/100 x 100-20/100

⇒ Selling Price =  15000 x 19/20 x 9/10 x 4/5 

⇒ 10260

∴ The Selling price is Rs. 10260.

Calculation:

Let the required value is y.

a

⇒ y = = 6/19

∴ The correct answer is 6/19.

Given

10 years ago the average age of 4 members of the family = 24 years.

The current average of 6 members is 24 years.

Formula used:

Sum of ages = Average age × Number of members

Calculation

Present total age of 4 members

⇒ 24 × 4 = 96 + (10 × 4) = 136

Preset total age of 6 members (including 2 children)

⇒ 24 × 6 = 144

Sum of the ages of the two children

⇒ 144 - 136 = 8 yrs.

Since the difference b/w age of two children is 2 year

⇒ The ages of the children are 5 yrs & 3 yrs.

∴ The youngest child's age is 3 years old.

The logic followed here is:

So, '63' is the next number in the given series.
Hence, the correct answer is "Option 4".

Given Statements:
A. Some leopards are buffaloes.
B. Some deer are mare.
C. All mare are fawn.
The least possible Venn diagram for the given statement is:

Conclusion:

(I) Some deer are buffalo → False (Because there is no direct relation given between deer and buffalo, so it can be possible but not definitely true.)
(II) Some fawn are deer → True (Because it is given that some deer are mare and all mare are fawn, so definitely there is some part of fawn which is deer.)
(III) Some leopards are mare → False (Because there is no direct relation given between leopards and mare, so it can be possible but not definitely true.)
So, only conclusion II follows.
|Hence, the correct answer is "Option A".

Family Chart:

Given
M is the brother of N.
L is the father of M.
N is the sister of O.
O is the daughter of P.

So, P is mother of N.
Hence, the correct answer is "Option A".

The correct answer is Cache memoryKey Points

• The correct answer is Cache memory.
• Quick Access: Cache memory stores copies of frequently used data coming from the slower main memory (RAM). It's closer to the CPU, which makes fetching commands quicker and overall process much faster. Utilizing cache improves system performance because it can access this data faster than it could from the main memory.
• Temporal Locality: Cache memory operates on the principle of locality of reference, specifically the temporal locality, which states that if data is referenced once, it's likely to be referenced again soon. Therefore, storing this frequently used data in cache reduces time-consuming operations and increases efficiency.
• Different Levels: There are different levels of cache memory (L1, L2, L3) with varying sizes and speeds. L1 cache is the smallest and fastest, located inside the processor chip. L2 and L3 caches are bigger and slightly slower, but still much faster than accessing data from RAM or a hard drive. The different levels allow systems to effectively optimize speed and cost.
