AEES PRT Mock Test - 7 - AEES PRT MCQ

A ratio equivalent to 3 : 7 is:
To find a ratio equivalent to 3 : 7, we need to find a pair of numbers that have the same ratio when simplified. Let's try the options:

(i) 3 : 9 → This simplifies to 1 : 3, not the same as 3 : 7
(ii) 6 : 10 → This simplifies to 3 : 5, not the same as 3 : 7
(iii) 9 : 21 → This simplifies to 3 : 7, which is the same as 3 : 7, so the answer is (iii).

Let the number be x. Then,

Using Rule 1 :
1st number × 2nd number = L.C. M. × H.C.F,
We have,
First number × second number = LCM × HCF

Let AB be the light house and the two boats be at C and D

∴ AB = 125 m

tan30° = BC/AB = x/125 = 1/3

=> x = 72.17 m

tan45° = BD/AB = y/125 = 1

=> y = 125 m

∴ The distance between the two boats is = x + y

= 72.17 + 125

= 197.17 m

NEP 2020 emphasizes the role of teachers in promoting critical thinking, creativity, and holistic development of students.

A lively classroom is the one having frequent student-teacher discussions. This is the two-way teaching method.

The stage of the embryo which nearly resembles a human being is called a fetus. Learning starts at fetal stage when a child starts reacting to different stimuli, as the sense organs are developed by this time.
The fetal nervous system starts developing very early in pregnancy. The main subdivisions of the brain are, in a basic form, visible at five gestational weeks. At about gestational weeks 25-29, the fetus is even able to hear internal (e.g. from the maternal gastrointestinal system) and external sounds. So, obviously the fetus gets a vague idea from the external environment through its senses, far before birth. Some studies even demonstrate that fetal heart rate patterns change distinctively, depending on whether the unborn child is exposed to the maternal voice or another female voice.

Answer: C - Provocation

Explanation:

- Fear is an emotional response to a perceived Threat.
- Similarly, Anger is an emotional response to a perceived Provocation.

A. Compulsion is not related to the cause of anger.
B. Panic is another form of fear, not a cause of anger.
D. Force can sometimes cause anger, but provocation is a more general term that better fits the analogy.

Explanation:

The correct answer is C: Get along.

Phrasal verbs are verb phrases that consist of a main verb and a preposition or adverb, which together create a specific meaning different from the main verb on its own. In this case, the phrase "get along" means to have a harmonious or friendly relationship with someone.

- A: Get off - This phrasal verb means to leave or disembark from a vehicle or place, and it is not suitable for the context provided.
- B: Get away - This phrasal verb means to escape or go on vacation, which also doesn't fit the context.
- C: Get along - This is the correct answer because it refers to having a good relationship with someone, as mentioned earlier.
- D: Get down - This phrasal verb means to dance or feel depressed, and it is not relevant to the given context.

The given sentence is in Active voice. Note that the tense of the verb in the given sentence should not be changed while changing the voice of the sentence.

Unconnected not joined together or to something else.
Chaotic : in a state of complete confusion and disorder.
Unaccountable : unable to be explained; Inexplicable.
Confusing : bewildering or perplexing.
Inexplicable : unable to be explained or accounted for.

Synonym of Inexplicable is Unaccountable

As we can say that ,
Prolific means fecund or very productive, Barren means unproductive, reckless is wildly impulsive, profound is something with much depth (of meaning).
Therefore , Barren is antonym word of Prolific . 

As we can say that ,
Tangible means available physically, concretely, elusive is something that eludes, i.e, is difficult to catch, touch or understand, palpable is a synonym to tangible.
Hence , Elusive is antonym word of Tangible . 

The idea is to express that it is the first time that Oxford has allowed public to vote. Thus, only ‘history’ is the best fit while ‘course’ and ‘age’ are incorrect.

Hence, the correct answer is option D.

cos(θ)=sin(90-θ)
so 40+A+30=90
A=20

Curved surface area of a cylinder = 2πrh

Hence, Option B is correct.

6cot+2cosec=cot+5cosec
6cot-cot=5cosec-2cosec
5cot=3cosec
5cos/sin=3/sin
cos=3/5

Position vector of A = OA = a
Position vector of B = OB = b
Now, AC = OC - OA
Also, AB = OB - OA
Given, AC = 3AB
⇒ OC - OA = 3(OB - OA)
⇒ OC = 3b - 2a

According to definition of parabola , is is the locks of the points in that planes that are equidistant from both focus and directrix.

Given, focus : (-3,0)
directrix : x + 5 = 0
Let (x ,y) is the point on the parabola .
∴ distance of point from focus = distance of point from directrix
⇒ √{(x + 3)² + y²} = |x + 5|/√(1² + 0²)
⇒ √{(x + 3)² + y² } = |x + 5|
squaring both sides,
(x + 3)² + y² = (x + 5)²
⇒y² = (x + 5)² - (x + 3)²
⇒y²= (x + 5 - x - 3)(x + 5 + x + 3)
⇒y² = 2(2x + 8) = 4(x + 4)

Hence, equation of parabola is y² = 4(x + 4)

Option A: If n is integer similarly n²- 1 is not divisible by 8.
Option B: If n is a natural number then it is not possible for n=1,2.
Option C: If n is odd the possible for n is 3,5,7...
Option D: If n is even then it is not possible for n=2.

Thus, the option C is correct.

As the number 2m will always be even, so if we add 1 to it then, the number will always be odd.

√9 is a rational number because √9 = 3 and 3 is a rational number.

Diagonal of a room = √(l² + b² + h²)
So the answer = √(20² + 10² + 20²) = √900 = 30 meters
Hence, Option B is correct.

ZnO(s) + CO(s) → Zn(s) + CO₂(g)

• Since oxygen has combined with carbon, carbon is the one that is oxidized and ZnO is the oxidizing agent. Similarly carbon has taken the oxygen of ZnO, carbon is the reducing agent and ZnO is the one that has been reduced.
• Reducing agent-C
• Oxidizing agent-ZnO
• Oxidized-CO
• Reduced- ZnO

So Option C is correct
