The triangle is rotating in clockwise direction by 45° and is shaded in alternate steps.

In alternate steps, we have a circle and a semicircle.

The diamond shape is rotating by 90° in the anticlockwise direction. So, in the next figure it should be exactly above the semicircle i.e. in the north.

Hence, option 1 is the correct answer.

These are the Ranks in an Army arranged in descending order.

2. Field Marshal
3. General
4. Brigadier
5. Colonel
6. Lieutenant

Hence, 2, 5, 3, 1, 4 is the correct answer.

Additional Information

Field Marshal > General > Lt. General > Major General > Brigadier > Colonel > Lt. Colonel > Major > Captain > Lieutenant (all post)

In the second and third positions we can observe:

1 and 2 are adjacent to 6

1 and 2 are adjacent to 3.

Therefore, 6 and 3 are on the opposites faces of the dice.

Hence, 3 is the correct answer.

The pattern followed here is,

(Second number) ³ + (first number) ² = third number

Like,

(7)³ + (8)² = 343 + 64 = 407

Similarly

(6)³ + (9)² = 216 + 81 = 297 = 297

Hence, (9, 6, 297) is the correct answer.

The pattern followed here is,

Hence, 115 is the correct answer.

The pattern followed here is,

4209 : 15 → 4 + 2 + 0 + 9 = 15

7456 : 22 → 7 + 4 + 5 + 6 = 22

5121 : 12 → 5 + 1 + 2 + 1 = 9 ≠ 12

8101 : 10 → 8 + 1 + 0 + 1 = 10

Hence, 5121 : 12 is the odd one out.

Concept Used:

 $Triangles = n× {{n + 1} \over2}×H$

Where, 

n= number of small triangles

H = number of ‘end to end’ horizontal lines

→ In, ∆ABC:12

n= number of small triangles = 2

H = number of ‘end to end’ horizontal lines = 4 (BC, HI, FG, and DE)

$Triangles = 2× {{2 + 1} \over2}×4 = 12$

Hence, Total triangles in ∆ABC = 12

→ In, ∆GJC: 9

n= number of small triangles = 2

H = number of ‘end to end’ horizontal lines = 3 (GJ, EK, ML)

$Triangles = 2× {{2 + 1} \over2}×3 = 9$

Hence, Total triangles in ∆GJC = 9

→ Now, remaining Triangles: 1 (∆AGJ)

→Now, triangles formed due to joining shapes= 3 (∆ANJ, ∆AFJ, ∆ACJ)

→ Now Adding all the ∆s:

Total ∆s = 12 + 9 + 1 + 3 = 25

Hence, “25” is the correct answer.

The pattern followed here is

For consonants, positional value - 3

For vowels, positional value + 3

Similarly,

Hence, SLRILK is the correct answer.

The pattern followed here is

For consonants, positional value - 3

For vowels, positional value + 3

No. of students passed in both English and History only = 12

No. of students passed in History = 50

No. of students passed in all three subjects = 5

No. of students who passed in Economics only = 100 - (50 + 24 + 11) = 100 - 85 = 15.

Hence, 15 is the correct answer.

Given equation: 28 – 32 ÷ 2 × 8 + 34 = 132

1. × and -; 32 and 34

Interchanging according to the option

 28 × 34 ÷ 2 – 8 + 32

= 28 × 17 – 8 + 32

= 476 – 8 + 32

= 500 ≠ 132

2) + AND -; 32 and 34

Interchanging according to the option

28 + 34 ÷ 2 × 8 – 32

= 28 + 17 × 8 – 32

= 28 + 136 – 32

= 164 – 32

= 132

3. • and -; 28 and 32

Interchanging according to the option

32 + 28 ÷ 2 × 8 – 34

= 32 + 14 × 8 – 34

= 32 + 112 – 34

= 144 – 34

= 110 ≠ 132

4. × and -; 8 and 2

Interchanging according to the option

28 × 32 ÷ 8 – 2 + 34

= 28 × 4 – 2 + 34

= 112 – 2 + 34

= 146 – 2

= 144 ≠ 132

Hence, + AND -; 32 and 34 is the correct answer.

= 42 × 6 = 252,

37 × 24 ÷ 3

= 37 × 8 = 296,

Similarly,

45 × 36 ÷ 3

= 45 × 12 = 540.

Hence, 45 is the answer.

The pattern followed here is second number = (first number × 8) + 5

109 = (13 × 8) + 5 = 104 + 5 = 109

Similarly,

? = (24 × 8) + 5 = 192 + 5 = 197

? = 197

Hence, 197 is the correct answer.

Pancreas, Liver, Kidney are organs in our body whereas Renin is an enzyme which is secreted by kidney.

(a + b + c - d)² - (a - b - c + d)²

Put a = b = c = d = 1, then

⇒ (1 + 1 + 1 - 1)² - (1 - 1 - 1 + 1)²

⇒ 2² - 0

⇒ 4

From the option 1

4a (a + c - d)

⇒ 4 × 1 (1 + 1 - 1)

⇒ 4

x - 1/x = 11

As we know,

⇒ (x - 1/x)³ = x³ - 1/x³ - 3 (x - 1/x)

⇒ 11³ = x³ - 1/x³ - 3 × 11

⇒ 1331 = x³ - 1/x³ - 33

⇒ x³ - 1/x³ = 1331 + 33

⇒ x³ - 1/x³ = 1364

Ratio of amount of Sunita, Amit and Vibha = 2 : 3 : 4

⇒ 4 unit = 14416

Short Trick:

Height of sixth boys = 175 + 1 × 6 = 181

Detailed Method:

Average height of 5 boys = 175

Sum of height of 5 boys = 175 × 5 = 875

Average height of 6 boys = 176

Sum of height of 6 boys = 176 × 6 = 1056

∴ Height of 6^th boy = 1056 – 875 = 181

In right-angled ΔPAT, 90 at A.

PT² = AP² + AT²

⇒ 10² = 6² + AT²

⇒ AT² = 100 - 36 = 64

⇒ AT = √64

⇒ AT = 8 cm

As we know,

AT = TR = 8 cm [common tangent]

⇒ TR = TB = 8 cm [common tangent]

As we know,

Perimeter of the square = 4a

Area of square = a²

⇒ 4a = 64

⇒ a = 64/4 = 16

∴ Area of square = 16² = 256

Let the price of the sugar be Rs. 5

Increased price of sugar = 5 × (6/5) = Rs. 6

Ratio of the price of sugar before to increased = 5 : 6

As we know,

Consumption is inversely proportional to price.

Ratio of consumption of price before to after = 6 : 5

∴ Required percentage = (6 - 5)/6 × 100 = $16\frac{2}{3}\%$

Concept Used:

The measure of angles is the same when the angles on the circumference cover the same arc. 

Calculation:

∠KLN = 58

As we know,

⇒ ∠KMN = ∠KLN = 58

tanθ - cotθ= cosecθ

⇒ Put θ = 60

tan60 - cot60 = cosec60

⇒ √3 - 1/√3 = 2/√3

⇒ 2/√3 = 2/√3 [satisfied]

Now,

$\frac{{2tan\theta - cos\theta }}{{\sqrt 3 cot\theta + sec\theta }}$

$\Rightarrow \frac{{2tan60 - cos60}}{{\sqrt 3 cot60 + sec60}}$

$\Rightarrow \frac{{2 \times \sqrt 3 - \frac{1}{2}}}{{\sqrt 3 \times \frac{1}{{\sqrt 3 }} + 2}}$

$\Rightarrow \frac{{\frac{{4\sqrt 3 - 1}}{2}}}{{1 + 2}}$

$\Rightarrow \frac{{\frac{{4\sqrt 3 - 1}}{2}}}{3}$

$\Rightarrow \frac{{4\sqrt 3 - 1}}{6}$

Calculation:

-1 +1/4 ÷ 1/2 × 2 + 5

⇒ -1 +1/4 × 2 × 2 + 5

⇒ - 1 + 1 + 5

⇒ 5

∴ Option 4 is the correct answer.

Total number of students = 32 + 18 + 28 + 45 + 42 + 42 + 13 + 30 = 250

Students studying in science = 32 + 18 = 50

Percentage of students studying in science = 50/250 × 100 = 20%

∴ Percentage of students studying other than science = 100 - 20 = 80%

Cost price of the dining table = Rs. 11900

SP of the dining table = 11900 × (120/100) = 14280

⇒ 2 unit = 20 × 2 = 40°

Cost price of the laptop = 42000

Profit gain on laptop = 42000 × 10/100 = 4200

Cost price of the scanner – cum – printer = 8000

Profit gain on scanner – cum – printer = 8000 × (5/100) = 400

Total profit = 4200 + 400 = 4600

Total cost price of both articles = 42000 + 8000 = 50000

∴ Profit percentage = 4600/50000 × 100 = $9\frac{1}{5}\%$

Total arrears of all five employees = 5500 + 4500 + 4000 + 3000 + 1500 = 18500

⇒ x = 12 days

$√ {{{\tan }^2}60^\circ + \sin 90^\circ - 2tan45^\circ }$

⇒ √[(√3)² + 1 – 2 × 1]

⇒ √[3 + 1 – 2]

⇒ √[4 – 2]

⇒ √2

As we know,

AD/DB = AE/EC

⇒ 2.5/3.5 = AE/4.2

⇒ AE = 4.2 × 5/7

⇒ AE = 3

⇒ AC = AE + EC

∴ AC = 3 + 4.2 = 7.2

Amount will become in 4 years = 73205

Amount will become in 3 years = 66550

Interest = 73205 - 66550 = 6655

∴ Rate of interest = 6655/66550 × 100 = 10%

Train A travels alone for 20 minutes (1/3 hour) → Distance = 48 × (1/3) = 16 km.

Remaining distance at 6:20 a.m. = 428 − 16 = 412 km.

Relative speed = 48 + 55 = 103 km/h.

Time to meet = 412 ÷ 103 = 4 hours after 6:20 a.m.

∴ The correct answer is 10:20 a.m.

Alternate Method

Given: Total Distance = 428 km, Speed of Train A = 48 km/h (starts 6:00 a.m.), Speed of Train B = 55 km/h (starts 6:20 a.m.).

Formula Used: Distance = Speed × Time; Relative Speed (Opposite direction) = S₁ + S₂.

⇒ Distance covered by Train A in 20 mins = 48 × (20/60) = 16 km.

⇒ Distance between trains at 6:20 a.m. = 428 − 16 = 412 km.

⇒ Relative speed = 48 + 55 = 103 km/h.

⇒ Time taken to meet = 412 ÷ 103 = 4 hours.

⇒ Meeting time = 6:20 a.m. + 4 hours = 10:20 a.m.

∴ The correct answer is 10:20 a.m.

Additional Information

Relative Speed Concept

When two objects move toward each other, their relative speed is the sum of their individual speeds: S_rel = S₁ + S₂.

Meeting Time Rule

To calculate meeting time, ensure both objects start moving from their respective positions at the same reference time by calculating initial distance covered.

Unit Conversion

Always convert time into hours when speed is in km/h: 1 minute = 1/60 hour.

The correct answer is option 3 i.e. ACBD

The passage begins with statement A which talks about how there are too many gadgets that are operated by remote control, then comes statement C which talks about how the remote control functions - once the button is pressed, a chip sets off an electronic vibration, then comes statement B which talks about the process further - the vibration causes an infrared beam that is made up of electromagnetic waves and finally comes statement D, this talks about how the waves carry coded signals for the operating systems.

Thus, the correct answer is option 3.

The correct answer is option 2 i.e. follow 

The sentence refers to citizens doing something in order to fight corruption and this cannot be 'disobeying' rules and regulations, nor can it be 'breaking' rules and regulations and it also cannot be 'rejecting' rules and regulations. It can only be achieved by 'following' rules and regulations.

Thus, the correct answer is option 2.

The correct answer is 'Option 2'.

Key Points

• The correct answer is "a good command over".
• In English, when you want to express proficiency in a language, you use the preposition "over" or "of" after "command".
• So the phrase should be "Amit has a good command over English" or "Amit has a good command of English".

Therefore, the correct sentence is*: "Amit has a good command over English as he was born and brought up in England."*

Additional Information

• Here is why the other options are incorrect:
• "A better command of" - This would be correct if we were comparing Amit's command of English to someone else's. But the sentence does not make any such comparison.
• "The best command in" - This is not correct. The phrase is either "command of" or "command over". The word "best" implies comparison, but the sentence does not compare Amit's command of English to anyone else's.

The correct answer is option 3 i.e. definite

The other spellings, 'Definete', 'Definiet' and 'Definate' are incorrect.

Thus, the correct answer is option 3.

The correct option is Lucy has already

Key Points

• The structure for the past perfect tense is had + [past participle].
• When you’re talking about some point in the past and are referring to two events then the event that occurred first must be in the perfect tense.
• The story above is written in the past tense. 'Lucy cut the cake' is the first event and 'their arrival' is the second event. So we have to use past perfect while talking about the first event.
• The other options are wrong as they make the sentence grammatically incorrect.
• Has already must be replaced with Had already. (Past perfect tense)

Hence, the correct sentence is: *'*Lucy had already cut the cake when we reached the party hall.'

The correct answer is option 3 i.e. major

The passage is talking about corruption and assuming that this is in reference to India, it is not a small problem, thus 'minor' is not an option. Corruption is not a living being and thus cannot be 'powerful' or 'strong'.

Thus, the correct answer is option 3.

The correct answer is option 4 i.e. eliminated

'Corruption' is not a good thing that should be 'created' or 'initiated' or 'permitted', it is like a disease that should be eliminated.

Thus, the correct answer is option 4.

The correct answer is option 3 i.e. fable

Fable: Refers to a short story that usually has animals and is used to convey a moral.

Let's look at the meaning of other words:

Ode: Refers to a lyric poem that addresses a particular subject

Parody: Refers to a performance that ridicules another performance

Hymn: Refers to a song of praise or worship

Thus, it is clear that option 3 is the correct answer

The correct answer is option 2 i.e. BACD

The passage begins with statement B, this talks about how all parts of the Earth are surrounded by air, then comes statement A which talks about what that air is called - atmosphere. This is followed by statement  C which talks about how living beings breathe and statement D names this process as 'respiration'.

Thus, the correct answer is option 2.

The correct answer is option 3 i.e. are utilized to the overall

The sentence refers to the responsibilities of a scientist and how their discoveries and inventions are used. 'Utilized' refers to being used and things are not used to development, they are used for development. Thus, the preposition 'to' needs to be replaced with 'for'

Thus, the correct answer is option 3.

The correct answer is option 4 i.e. The wild and mad elephant is claimed to have been seen in several cities.

Key Points

• The original sentence is in the active voice, the format for this will be:
• Subject + Present tense of the Verb + to have seen + Object
• This needs to be converted to the passive voice, the format for that will be:
• Object  + is + Third form of the verb + to have been seen + Subject
• The wild and mad elephant is claimed to have been seen in several cities.

Thus, the correct answer is option 4.

The correct answer is option 1 i.e. amiable

Hostile: Refers to someone who is cruel and maybe violent

Amiable: Refers to someone who is very kind and very friendly

Thus, the most suitable answer is Option 1)

The correct answer is option 2 i.e. announced

The sentence refers to the government's schemes - these are things that cannot be 'denounced' thus option 1 is incorrect, they cannot be 'concealed' either and so option 3 is incorrect and option 4 is incorrect because 'schemes' may or may not be 'written' but they only become schemes only if 'announced'.

Thus, the correct answer is option 2.

The correct answer is option 4 i.e. active

Sluggish: Refers to someone who is lazy and slow.

Active: Refers to someone who is energetic and fast.

Thus, it is clear that sluggish and active are opposite words.

• Harbinger: Refers to someone who announces the arrival of something.
  

Thus, the correct answer is option 3.

The correct answer is option 2 i.e. intention

The first sentence refers to corruption, and this is a something that is practised on purpose and is not something that is done out of a gut feeling - thus it cannot be 'intuition' and so option 3 is incorrect.No one forces someone to be corrupt, thus 'compulsion' - option 4 is incorrect. 'Corruption' is not a hobby or job that someone is passionate about, thus option 1 is incorrect.

Thus, the correct answer is option 2.

The correct answer is option  3 i.e. He asked me what time the banks opened and closed.

The original sentence has a question mark, thus the indirect sentence should have a verb like 'asked' or 'questioned', thus option 2 and 4 are incorrect because they use different verbs. option 1 cannot be used as reported speech is supposed to have verbs in the past tense, but option 1 uses the present tense.

Thus, the correct answer is option 3.

The correct answer is option 4 i.e. To make a bad situation worse

The idiom 'to put fuel to the fire' refers to the act of making an already bad situation worse. 

Thus, the correct answer is option 4.

The correct answer is option 3 i.e. I were the.

Key Points:- 

• The sentence is in a subjunctive mood -  The subjunctive mood is the verb form used to explore a hypothetical situation (e.g., If I were you) or to express a wish, a demand, or a suggestion (e.g., I demand he be present).
• Thus, in subjunctive mood statements, the verb is always 'were' even for a singular person.
• Thus, the correct answer is option 3.
