  • There are two verbs which are present in sentence B and C i.e. 'be' and 'live' if we connect this sentence with 'B' then it makes a coherent sentence.
  • Similarly, 'you' is the subject for this we need a verb which is written in sentence 'C'.

2

Why this answer is correct

The correct answer is 'Option 3'

Key Points

Key Points

  • In part 3 of the sentence, the use of 'was' is incorrect Instead, use 'were'
  • According to the rule of subject-verb agreement, the verb should be plural if the subject of the sentence is plural.
  • ​For example- We were happy with the review of our first movie.
  • In the given sentence, the subject is 'marks' hence the verb should be 'were'
  • 'Due to' is a preposition and 'the snow' is the prepositional object hence there is no effect on the verb of 'the snow'.

So the correct sentence is- Due to the snow the marks were unrecognisable.

Why this answer is correct

    71

  2. BOption (b)

    68

  3. COption (c)

    70

  4. DOption (d)

    65

View answer & explanation

Correct answer

Answer: (a)A.

71

Why this answer is correct

According to the question,

Ratio of ages of Ankur's sister and his brother after 6 years → 3 : 2 

So, let the ages of Ankur's sister and his brother after 6 years be 3x and 2x respectively.

Present age of Ankur's brother → 32 years

Age of Ankur's brother after 6 years → 32 + 6 = 38 years 

Now, equating 2x = 38 (as the age of Ankur's brother after 6 years is 38)

x = 19

Present age of Ankur's sister → 3x - 6

(3 × 19) - 6 → 57 - 6 = 51

It is also given that the ratio of the present ages of Ankur and his sister is 4 : 3

So, let the present ages of Ankur and his sister be 4y and 3y respectively.

Now, equating 3y = 51 (as the present age of Ankur's sister is 51)

y = 17

Present age of Ankur → 4y 

4y → 4 × 17 = 68

Age of Ankur after 3 years → 68 + 3 = 71

Hence, the correct answer is "71".

Why this answer is correct

Given word → STATEMENT

  1. Men → STATEMENT (it is possible to form the word)
  2. Same → STATEMENT (it is possible to form the word)
  3. Start → Letter ‘R’ is not present in the word STATEMENT therefore, it is not possible to form the word Start.
  4. State → STATEMENT (it is possible to form the word)

It is clear from above that the word Start cannot be formed using the letters of the given word.

Hence, the correct answer is "Start".

12 + 10 - 28 ÷ 7 × 4 = 48

Checking options one by one by interchanging signs:-

    • and -

12 - 10 + 28 ÷ 7 × 4 = 48

Now, after applying BODMAS Rule, we get:-

12 - 10 + 28 ÷ 7 × 4 = 48

12 - 10 + 4 × 4 = 48

12 - 10 + 16 = 48

12 + 16 - 10 = 48

28 - 10 = 48

18 ≠ 48

Left hand side is not equal to right hand side.

2) + and ÷

12 - 10 + 28 ÷ 7 × 4 = 48

Now, after applying BODMAS Rule, we get:-

12 - 10 + 28 ÷ 7 × 4 = 48

1.2 - 28 + 7 × 4 = 48

1.2 - 28 + 28 = 48

1.2 + 28 - 28 = 48

Now, after applying BODMAS Rule, we get:-

12 - 10 + 28 ÷ 7 × 4 = 48

12 - 10 + 4 × 4 = 48

12 - 10 + 16 = 48

12 + 16 - 10 = 48

28 - 10 = 48

18 ≠ 48

Left hand side is not equal to right hand side.

4) × and -

12 + 10 × 28 ÷ 7 - 4 = 48

Now, after applying BODMAS Rule, we get:-

12 + 10 × 28 ÷ 7 - 4 = 48

12 + 10 × 4 - 4 = 48

12 + 40 - 4 = 48

52 - 4 = 48

48 = 48

Left hand side is equal to right hand side.

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

As per the logic,

First Number = 2

Second Number = 22

Third Number = 4444 → Doesn't satisfies the logic.

3) (4, 44, 4444):

As per the logic,

First Number = 4

Second Number = 44

Third Number = 4444

4) (8, 88, 8888):

As per the logic,

First Number = 8

Second Number = 88

    280/11

  3. COption (c)

    179/7

  4. DOption (d)

    172/7

View answer & explanation

Correct answer

Answer: (c)C.

179/7

Why this answer is correct

Shortcut Trick

Total Work (LCM of 20, 35) = 140 units.

Efficiency: X = 7, Y = 4. 2-hour cycle (Y + X) = 4 + 7 = 11 units.

12 cycles (24 hours) = 12 × 11 = 132 units. Remaining = 140 − 132 = 8 units.

25th hour (Pipe Y): 4 units filled. Remaining = 4 units. Time for X = 4/7 hours.

Total Time = 24 + 1 + 4/7 = 25 + 4/7 = 179/7 hours.

∴ The correct answer is 179/7 hours.

Alternate Method

PipeTime (hrs)Total WorkEfficiency
X201407
Y354

⇒ Total Capacity = LCM(20, 35) = 140 units.

⇒ Efficiency of X = 140 ÷ 20 = 7 units/hr.

⇒ Efficiency of Y = 140 ÷ 35 = 4 units/hr.

⇒ Since they work on alternate hours starting with Y:

⇒ Work in 1st hour (Y) = 4 units; Work in 2nd hour (X) = 7 units.

⇒ Total work in 2 hours = 4 + 7 = 11 units.

⇒ Work done in 12 such cycles (24 hours) = 12 × 11 = 132 units.

⇒ Remaining work = 140 − 132 = 8 units.

⇒ On 25th hour, Y fills 4 units. Remaining = 8 − 4 = 4 units.

⇒ Time taken by X to fill last 4 units = 4/7 hours.

⇒ Total time = 24 + 1 + 4/7 = 179/7 hours.

∴ The correct answer is 179/7 hours.

Additional Information

Alternate Day/Hour Concept

In alternate work, tasks are calculated in cycles. The order of pipes/workers significantly changes the total time if the work is not a perfect multiple of the cycle's total efficiency.

Pipes and Cisterns

Efficiency is inversely proportional to time. Filling pipes have positive efficiency, while leakage or outlet pipes have negative efficiency.

View answer & explanation

Correct answer

Answer: (c)C.

Reserve Bank of India

Why this answer is correct

The correct answer is the Reserve Bank of India.

Key Points Deficit financing:

  • Deficit financing means generating funds to finance the deficit which results from an excess of expenditure over revenue.
  • The gap is covered by borrowing from the public through the sale of bonds or by printing new money.
  • For developing countries like India, higher economic growth is a priority.
  • Higher economic growth requires finances.
  • With the private sector being shy of making a huge expenditure, the responsibility of drawing financial resources rests on the government.
  • Often both the tax and non-tax revenues fail to mobilize enough resources just through taxes.
  • The deficit is often funded through borrowings or printing new currency notes.
  • Deficit financing affects investment adversely.
  • When there is inflation in the economy employees demand higher wages to survive.
  • If their demands are accepted it increases the cost of production which de-motivates the investors.

Important PointsReserve Bank of India (RBI)

  • RBI was established in India on 1st April, in Kolkata in 1935 under the Reserve Bank Of India Act, 1934.

Correct answer

Answer: (b)B.

8

Why this answer is correct

CONCEPT:

  • Force: Force is a push or pulls on an object. A force can cause an object to accelerate, slow down, remain in place, or change shape.

Force exerted = mass x acceleration

⇒ F = m × a

Acceleration = (Final velocity - Initial velocity)/time

⇒ a = (v2 - v1) / t

Where F is the force exerted on the body, m is the mass of the body, a is the acceleration of the body, v2 is the final velocity, v1 is initial velocity and t s time.

Calculation:

Given data:

the mass of the body m = 4 kg, Final velocity v2 = 25 m/s, Initial velocity v1 = 15 m/s, time t = 5 s.

We know that,

⇒ Acceleration = (Final velocity - Initial velocity)/time

a = (25 - 15)/5 m/s2 = 2 m/s2

Also,

⇒ Force exerted = mass x acceleration

⇒ Force = 4 × 2 = 8 N

  • So option 2 is correct.

Question 97

During ________ motion of an object along a straight line, the change in velocity of the object for any time interval is zero.

  1. AOption (a)

    Linear

  2. BOption (b)

    Translational

  3. COption (c)

    Equilibrium

  4. DOption (d)

    Uniform

View answer & explanation

Correct answer

Answer: (d)D.

Uniform

Why this answer is correct

The Correct answer is Uniform.

Explanation:

  • Uniform motion: The motion of an object in which the object travels in a straight line and its velocity remains constant along that line as it covers equal distances in equal intervals of time, irrespective of the duration of the time.
  • During the uniform motion of an object along a straight line, the change in velocity of the object for any time interval is zero and remains constant with time. In this case, the acceleration would also be equal to zero.
