The correct answer is 'invite'

Key Points

• In the given sentence, the usage of 'will invite' is incorrect instead of it use 'invite'
• According to grammar, whenever we have a main clause and subordinate clause in the conditional sentence, the usage of will is incorrect in the subordinate clauses hence, we need to omit 'will' from the subordinate clause.
• Let's see an example-
• Unless you call me to say you're not coming, I'll see you at the theatre (= I will see you there if you do not call to say you are not coming).

Hence, the correct sentence is- He won't come to the party unless you invite him personally.

Confusion Points

• The word "invited" is in the past tense, and using it in this context would imply that the invitation would have already occurred in the past. However, the sentence is speaking about a future event (the party) and a condition that must be met in the future (the personal invitation).
• The verb tenses in the two parts of this conditional sentence need to match. If the first part is in the future tense ("He won't come to the party"), then the second part also needs to be in a tense that refers to future action. The base form of the verb ("invite") is used here to express a condition in the present or future.
• If we were talking about a past event, "invited" could be correct. For example: "He didn't come to the party unless you invited him personally."
• So, "invite" is the correct option in this context.

The correct sequence is- DBAC

Key Points

• On reading the sentences, we can comprehend that the passage is giving a detailing of a person who has picked up a child who is younger than the person.
• Sentence D will be the first sentence as it introduces the speaker.
• Sentence B will be the second sentence as it tells that the speaker is picked up and made to sit on a tombstone.
• Sentence A will be the third sentence as it tells about the person who has picked up the child.
• Sentence C will be the fourth sentence as it is the only sentence left.

So the correct passage is- I was only a child, and small for my age. Suddenly I was picked up, whirled through the air, and made to sit on a tombstone. The man who had caught me was a dreadful sight. He was about forty years old, hard-faced and fierce.

The erroneous part is- 'Leave behind'

Key Points

• In the given sentence, the usage of 'leave' is incorrect instead of it use 'leaving'
• In the given sentence, the subject of the sentence is- Cyclone Amphan and the main verb is 'roared' 'into West Bengal' is a prepositional phrase 'on Wednesday' is also a prepositional phrase hence, we don't want a verb as the verb is already given.
• We need a participle as 'roar' is an intransitive verb so there is no need to use an object in the given sentence. The present participle will define the prepositional phrases because they are adverb phrases.
• Hence, the correct sentence is- Cyclone Amphan roared into West Bengal on Wednesday leaving behind a trail of devastation across a large area of the State.

The correct answer is as kind as

Key Points

• In the given sentence, the usage of 'kind as' is incorrect instead of this we need to use 'as kind as'
• The given sentence using a simile to compare the two persons i.e. Mr. Sharma and His father.
• Hence, we can use a simile for this 'as...as' strucure.
• Example- He is as busy as a bee
• Hence, the correct sentence is- Mr. Sharma is as kind as his father.

The correct answer is 'weighted'

Key Points

• Let's see the meanings of the given words-
• Buoyant- able or tending to keep afloat or rise to the top of a liquid or gas. किसी तरल या गैस के ऊपर उठने या ऊपर उठने में सक्षम या प्रवृत्त।

• Weighted- hold (something) down by placing a heavy object on top of it. उसके ऊपर कोई भारी वस्तु रखकर (किसी चीज को) नीचे रखना।
• Hence, according to the meanings of the words the correct answer is Option 4 i.e. Weighted.

The erroneous part is- 'more better if'

Key Points

• In the given sentence, the usage of 'more better' is incorrect instead of it use 'better'
• According to grammar, 'better' is used as a comparative degree of the positive degree of adjective 'good'. Hence, we can't use one more comparative degree before 'better'
• Let's see an example-
• The book was better than I expected.

Hence, the correct sentence is- It would be better if she sang with an orchestra.

• Cutlass- a curved sword with a single sharp edge, especially as used in the past by pirates (एक तेज धार वाली घुमावदार तलवार, विशेष रूप से अतीत में समुद्री लुटेरों द्वारा उपयोग की जाने वाली तलवार)
• Hence, according to the meanings of the given words, the correct answer is Option 1 i.e. Boomerang.

The correct answer is 'The plants are watered in the evening.'

Key Points

• The given sentence is in the active voice and the main verb of the sentence is 'water'
• 'water' can be used as a verb that means 'to pour water on to plants or the soil that they are growing in'

Given :- c k _ g k c _ t _ k _ k t g _ c k _ g k

By checking options and substituting accordingly.

1) t, k, g, c, c, t → c k t g k / c k t g k / c k t g c / c k t g k

2) t, k, c, g, k, t → c k t g k / c k t c k / g k t g k / c k t g k

3) t, k, g, c, k, t → c k t g k / c k t g k / c k t g k / c k t g k

4) t, g, k, c, k, t → c k t g k / c g t k k / c k t g k / c k t g k

Option (3) gives a pattern of cktgk - cktgk - cktgk - cktgk

• Here the option (3) represents the pattern as : c k t g k / c k t g k / c k t g k / c k t g k

Hence, the correct answer is "t, k, g, c, k, t".

Given Total number of students = 68

Number of students participated only in Debate = 34

Number of students participated in both Quiz and Debate = 8

If every student of the class has participated in at least one of these two competitions

Number of students participated only in Quiz = Total number of students - (Number of students participated only in Debate + Number of students participated in both Debate and Quiz)

• Number of students participated only in Quiz = 68 - (34 + 8)
• Number of students participated only in Quiz = 68 - 42 = 26

Number of students participated in quiz = Number of students participated only in Quiz + Number of students participated in both Quiz and Debate

∴ Number of students participated in quiz = 26 + 8 = 34

Hence, the correct answer is "34".

The logic followed here is :-

First number = Second number² + 6

Third number = Fourth number² + 6

Fifth number = Sixth number² + 6

127 : 11 → 11² + 6 = 121 + 6 = 127

and 

367 : 19 → 19² + 6 = 361 + 6 = 367

Similarly,

 ? : 16 → 16² + 6 = 256 + 6 = 262

∴ The relation so formed is : 127 : 11 :: 262 : 16 :: 367 : 19

Hence, the correct answer is "262".

The logic followed here is :-

Astronomy is the study of Stars and universe everything in universe beyond earth's atmosphere.

Important Points1) Philology → Philology is study of language of oral and written historical sources.

2) Seismology → Seismology is study of earthquakes and seismic waves that moves through and around earth.

4) Psychology → Psychology is scientific study of mind and behavior.

The logic follows here is :-

1) HNTZ

2) IPVA

3) VBHN

4) AGMS

∴ IPVA is different from the other three alternatives.

Hence, the correct answer is "IPVA".

Family Chart :

'A & B' → 'A is the father of B'

'A @ B' → 'A is the sister of B'

Family tree:

1) H @ K @ P & M

Here H is the aunt of M.

2) K & H @ P @ M

Here H is the sister of M.

3. M & K @ P @ H

Shortcut Trick The common chord AB is bisected by the line of centres OP at M, so AM = 8 cm. Using Pythagorean triplets for right-angled triangles ΔAMO and ΔAMP: For ΔAMO (hypotenuse 17, leg 8): OM = √(172 − 82) = 15 cm. For ΔAMP (hypotenuse 10, leg 8): PM = √(102 − 82) = 6 cm. Distance between centres OP = OM + PM = 15 + 6 = 21 cm. Perimeter of ΔOAP = OA + AP + OP = 17 + 10 + 21 = 48 cm. ∴ The correct answer is 48 cm.

Alternate Method Given: Radius of first circle (centre O), OA = 17 cm Radius of second circle (centre P), PA = 10 cm Length of common chord, AB = 16 cm

Formula Used: The line joining the centres of two intersecting circles is the perpendicular bisector of their common chord. Pythagoras Theorem: Hypotenuse2 = Base2 + Perpendicular2 Perimeter of triangle = Sum of all three sides

Calculations: Let the line joining the centres O and P intersect the common chord AB at point M. ⇒ AM = MB = AB ÷ 2 ⇒ AM = 16 ÷ 2 = 8 cm Since OP is perpendicular to AB, ΔAMO and ΔAMP are right-angled triangles at M. In right-angled ΔAMO, using Pythagoras theorem: ⇒ OA2 = OM2 + AM2 ⇒ 172 = OM2 + 82 ⇒ 289 = OM2 + 64 ⇒ OM2 = 289 − 64 = 225 ⇒ OM = √225 = 15 cm In right-angled ΔAMP, using Pythagoras theorem: ⇒ PA2 = PM2 + AM2 ⇒ 102 = PM2 + 82 ⇒ 100 = PM2 + 64 ⇒ PM2 = 100 − 64 = 36 ⇒ PM = √36 = 6 cm Now, the distance between the centres OP is: ⇒ OP = OM + PM ⇒ OP = 15 + 6 = 21 cm We need to find the perimeter of ΔOAP: ⇒ Perimeter of ΔOAP = OA + AP + OP ⇒ Perimeter of ΔOAP = 17 + 10 + 21 = 48 cm

Why other options are incorrect: ⇒ Option (1) 40 cm: This value does not correspond to any valid geometric configuration of the given circles. ⇒ Option (3) 25 cm: This is incorrect as the sum of the two radii alone is 17 + 10 = 27 cm, so the perimeter of the triangle must be greater than 27 cm (since OP > 0). ⇒ Option (4) 33 cm: This does not match either of the mathematically possible perimeters (48 cm or 36 cm) derived from the circle properties.

∴ The correct answer is 48 cm.

Additional Information Perpendicular Bisector Property The line segment connecting the centres of two intersecting circles is always the perpendicular bisector of their common chord. Alternative Case (Centres on Same Side) If the centres of the circles lie on the same side of the common chord, the distance between the centres is OP = OM − PM = 15 − 6 = 9 cm. In this case, the perimeter of ΔOAP would be 17 + 10 + 9 = 36 cm. Pythagorean Triplets Common integer right-triangle side sets like (8, 15, 17) and (6, 8, 10) help solve competitive exam geometry questions extremely quickly without full calculation.

If sec θ = cosec θ, then θ = 45° (since sin θ = cos θ only at 45° for acute angles).

Substitute θ = 45° in the given expression: sec² 45° + cosec² 45°.

Value = (√2)² + (√2)² = 2 + 2 = 4.

∴ The correct answer is 4.

Alternate Method

Given: sec θ − cosec θ = 0, where θ is an acute angle.

Formula Used: sec θ = 1/cos θ | cosec θ = 1/sin θ | tan θ = sin θ/cos θ.

⇒ sec θ − cosec θ = 0

⇒ sec θ = cosec θ

⇒ 1/cos θ = 1/sin θ

⇒ sin θ = cos θ

⇒ sin θ / cos θ = 1

⇒ θ = 45°

Now, calculate sec² θ + cosec² θ:

⇒ sec² 45° + cosec² 45°

⇒ (√2)² + (√2)²

⇒ 2 + 2 = 4

∴ The correct answer is 4.

Additional Information

Complementary Angle Property

Trigonometric functions satisfy sec θ = cosec (90° − θ). If sec α = cosec β, then α + β = 90°.

Shortcut Trick

Speed ratio = 100 : 125 = 4 : 5

Time ratio (for same distance) = inverse of speed ratio = 5 : 4

Initial time 5 units = 50 minutes ⇒ 1 unit = 10 minutes

Time for full distance at new speed = 4 units = 40 minutes

Time for 3/4 distance = 3/4 × 40 minutes = 30 minutes

∴ The correct answer is 30 minutes.

Alternate Method

Given:

Initial speed (S₁) = 54 km/h

Initial time (T₁) = 50 minutes = 50/60 hours

Formula used: Distance = Speed × Time

Start End Total Distance (D)

3/4 of Distance Speed 1: 54 km/h Speed 2: 54 + 25% = 67.5 km/h

⇒ Total Distance = 54 × (50/60) = 45 km

⇒ New Speed = 54 + (25/100) × 54 = 54 + 13.5 = 67.5 km/h

⇒ New Distance = 3/4 × 45 = 33.75 km

⇒ New Time = New Distance ÷ New Speed

⇒ New Time = 33.75 ÷ 67.5 = 0.5 hours

⇒ New Time in minutes = 0.5 × 60 = 30 minutes

∴ The correct answer is 30 minutes.

Additional Information

Speed-Time Relationship

For a constant distance, speed is inversely proportional to time (S₁/S₂ = T₂/T₁).

Given:

tan A + sec A = $\frac{3}{2}$

Concept used:

sec² A - tan² A = 1

a² - b² = (a + b)(a - b)

Calculation:

sec A + tan A= $\frac{3}{2}$      ----(i)

Ratio of Salaries Reena (R) : Sunita (S) = 38 : 24 = 19 : 12

Total units (R + S) = 19 + 12 = 31 units

Veena’s salary = 2/3 × 31 units = 62,000

31 units = 62,000 × 3/2 = 93,000 ⇒ 1 unit = 3,000

Sunita’s salary (12 units) = 12 × 3,000 = 36,000

∴ The correct answer is Rs. 36,000.

Alternate Method

Given:

24% of Reena’s salary (R) = 38% of Sunita’s salary (S)

Veena’s salary (V) = 2/3 × (R + S) = 62,000

Formula Used:

Ratio = Value₁ / Value₂

Reena (19 units) Sunita (12 units) Total (R + S) = 31 units Veena = 2/3 of Total = Rs. 62,000 Sunita (12 units) = ?

⇒ 24% × R = 38% × S

⇒ R / S = 38 / 24 = 19 / 12

⇒ Let R = 19x and S = 12x

⇒ V = (2/3) × (19x + 12x) = 62,000

⇒ (2/3) × 31x = 62,000

⇒ 31x = 62,000 × (3 / 2)

⇒ 31x = 93,000

⇒ x = 93,000 / 31 = 3,000

⇒ Sunita’s salary = 12x = 12 × 3,000 = 36,000

∴ The correct answer is Rs. 36,000.
