Dry deserts:

• Deserts are dry places where little or no rainfall occurs.
• Some deserts get less than 25 mm (1 inch) of precipitation each year.
• Desert soil is often sandy, rocky, or gravely.
• Plantlife is highly specialized to adapt to these coarse, dry conditions, with long roots, small leaves, stems that store water, and prickly spines that discourage animals from touching or eating them.
• A cactus is a kind of plant adapted to hot, dry climates, i.e deserts.

Hence, option 1 is the correct answer.

​​​​Tundra region:

• ​Tundra regions typically get less than 25 cm of precipitation annually.
• It means these areas are also considered deserts.
• They have long, cold winters with high winds and average temperatures below the freezing point for six to ten months of the year.
• On average, only six to ten weeks of the year have sufficiently warm temperatures and long days for plant growth.

1) A man starts from his office and goes 8 km East.

2) Then he turns to the left and walks for 3 km.

All except 55 - 62 have difference of nine between them.

55 – 62 = difference is 7

34 – 43 = difference is 9

62 –71 = difference is 9

83 – 92 = difference is 9

Hence, 55-62 is correct answer.

Check with options one by one:

Given expression: 5 × 132 ÷ 11 - 28 + 70 = 18

1) - and ×

5 - 132 ÷ 11 × 28 + 70

= 5 - 12 × 28 + 70

= 5 - 336 + 70

= - 261 ≠ 18

2) ÷ and ×

5 ÷ 132 × 11 - 28 + 70

= 0.037 × 11 - 28 + 70

= 0.407 - 28 + 70

= 42.407 ≠ 18

3) + and -

5 × 132 ÷ 11 + 28 - 70

= 5 × 12 + 28 - 70

= 60 + 28 - 70

= 18

4) + and ×

5 + 132 ÷ 11 - 28 × 70

= 5 + 12 - 28 × 70

= 5 + 12 - 1960

= -1943 ≠ 18

Hence, "+ and -" is the correct answer.

Checking each option one by one:

Given equation: 18 * 12 * 4 * 5 * 6 = 53

1) +, -, ×, ÷

18 + 12 - 4 × 5 ÷ 6

= 18 + 12 - 4 × 0.833

= 18 + 12 - 3.33

= 26.67 ≠ 53

2) ×, -, ÷, +

18 × 12 - 4 ÷ 5 + 6

= 18 × 12 - 0.8 + 6

= 216 - 0.8 + 6

= 221.2 ≠ 53

3) ×, ÷, +, -

18 × 12 ÷ 4 + 5 - 6

= 18 × 3 + 5 - 6

= 54 + 5 - 6

= 53 = 53

4) ×, +, ÷, -

18 × 12 + 4 ÷ 5 - 6

= 18 × 12 + 0.8 - 6

= 216 + 0.8 - 6

= 210.8 ≠ 53

Hence, "×, ÷, +, -" is the correct answer.

As per the dictionary, the given words can be arranged as:

5. Venereology

4. Ventilator

2. Ventricle

3. Verbatim

1. Verification

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

1320 : 11 → 11³ – 11 = 1331 - 11 = 1320.

Similarly, 13³ - 13 = 2197 – 13 = 2184.

Hence, "2184" is the correct answer.

The pattern followed here is:

Therefore, “NOQS” is odd among them.
Hence, “NOQS” is the correct answer.

The pattern followed here is:

Similarly,

Hence, “UIUHV” is the correct answer.

Given:

Total distance = 160 km

Formula used:

Speed = Distance/Time

Time = Distance/Speed

Calculation:

(1/4)th of the distance = 40 km

Time taken to travel 40 km = 40/5

⇒ 8 hours

40 km travels in 8 hour

Remaining distance = 160 - 40

= 120 km

120 km covers in 4 hours (i.e. 12 - 8)hour

Speed = 120/4

= 30 km/h

Given:

Principal = Rs. 8000

Rate of interest = 30%

Time = 2 years

Formula used:

Amount = Principal(1 + R/100)^t

Calculation:

Rate of interest for 6 months = R/2 = 30/2 = 15%

Amount = Principal(1 + R/100)t

⇒ Amount = 8000 × (1 + 15/100)²

⇒ Amount = 8000 × (23/20) × (23/20)

⇒ Amount = 20 × 529

⇒ Amount = Rs. 10580

⇒ Interest = Amount – principal

⇒ Interest = 10580 – 8000 = Rs. 2580

∴ The simple interest is Rs. 2580

Given:
Prinicipal = Rs. 1,000
Amount = Rs. 1,331
Rate = 20% per annum
Formula used:
A = P {1 + (R/100)}^T
where, A = Amount, P = Principal, R = Rate and T = Time
Calculations:
For compounded half-yearly, Rate = (20/2)% = 10%
and Time will be 2T
According to the question, we have
A = P {1 + (R/100)}2T
⇒ 1,331 = 1,000 {1 + (10/100)}2T
⇒ (1,331/1000) = {1 + (10/100)}2T
⇒ (11/10)³ = (11/10)^2T
By equating both sides, we get
⇒ 2T = 3
⇒ T = 3/2
⇒ T =  years
∴ The time for Rs. 1,000 to amount to Rs. 1,331 at 20% per annum, compounded half - yearly is  years.

Given:

The volume of the cylinder = 1650 cm³

Height of the cylinder = 21 cm

The radius of the cylinder and sphere is equal.

Formula used:

Volume of the cylinder = πr²h

Volume of the sphere = (4/3) × πr³

Where,

V_c = Volume of the cylinder

V_s = Volume of the sphere

r = Radius of the cylinder and sphere

h = height of the cylinder

Calculation:

Volume of the cylinder = πr2h

⇒ 1650 = (22/7)× (r²) × 21

⇒ 25 = r²

⇒ r = 5 cm

Volume of the sphere = (4/3) × πr3

⇒ V_s = (4/3) × π × (5)³

⇒ Vs = (500π)/3 cm3

∴ The volume of the sphere is (500π)/3 cm³.

Key Points

• The given above sentence is grammatically incorrect.
• Use 'than' in the place of when.
• No sooner is used to show that one thing happens immediately after another thing and is usually followed by than.
• When ‘no sooner’ goes at the beginning of the sentence, we use an inverted word order. That means the auxiliary verb goes before the subject.
• Let's see the structural form of the given sentence:
  
  • No sooner did the teacher enter the classroom when the students stood up.
  • No sooner did the teacher enter the classroom than the students stood up.
• ​So, as per the given points, 'than' will be used instead of when.

Correct sentence: No sooner did I reach there than the rain rushed in making us shiver.

Note that Had + V3 is also possible in this structure.
Let's see the structure:

• No sooner had she finished one project than she started working on the next.
• No sooner had she finished one project when she started working on the next.

The correct answer is- 'cannot go anywhere'.

Key Points

• Double negative: A double negative occurs when two negative terms are used in the same sentence. These should be avoided.
  • Example: I didn't get no shoes.
• A double negative is usually created by combining the negative form of a verb (e.g., cannot, did not, have not) with a negative pronoun (e.g., nothing, nobody), a negative adverb (e.g., never, hardly), or negative conjunction (e.g., neither/nor).
  • Example: She did not have neither her address nor her phone number. (A negative verb with the negative conjunction neither/nor)
• The above-given sentence has double negatives, therefore 'cannot go nowhere' should be replaced with 'cannot go anywhere'.
• Hence, option 3 is the correct answer.

The correct sentence is: I cannot go anywhere on Monday.

The correct answer is Option 4 i.e Apex

• Let's look at the meaning of the given word and the correct option
