RRB Group D PYP Practice Test 22

1.Rs. 720 was divided among A, B, C, D, E. The sum received by them was in ascending order and in arithmetic progression. E received Rs. 40 more than A. How much did B receive?

A. Rs. 134

B. Rs. 154

C. Rs. 144

D. Rs. 124

Solutions

Let A receive Rs. a and let the difference between each consecutive person be Rs. d.

⇒ Amount received by E = a + 4d

According to question,

⇒ Amount received by E = Amount received by A + 40

⇒ a + 4d = a + 40

⇒ 4d = 40

⇒ d = 10

Also,

⇒ Total amount = a + (a + d) + (a + 2d) + (a + 3d) + (a + 4d)

⇒ 720 = 5a + 10d

⇒ 720 = 5a + 100

⇒ a = 124

⇒ Amount received by B = a + d = 124 + 10 = Rs. 134

Alternate Method

Calculation:

A, B, C, D and E 

As the amount received is in AP,

Difference in an amount of two consecutive members is the same.

⇒ B – A = C – B = D – C = E – D

We have E – A = 40, 

⇒ B – A = 10, C – B = 10, D – C  = 10, E – D = 10,

Let say A received Rs. x,

Then B, C, D and E will receive,

⇒ x + 10, x + 20, x + 30, x + 40

According to the question,

⇒ x + x + 10 + x + 20 + x + 30 + x + 40 = 720

⇒ 5x + 100 = 720

⇒ 5x = 620

⇒ x = 124

B will receive = x + 10 = 124 + 10 = 134

∴ B will receive amount of Rs. 134

34.In physics work done is defined as

  1. A force has acted on an object without causing any displacement of it.
  2. Object is displaced
  3. A force has acted on the object
  4. All of the above

A. B and C are correct

B. A and B are correct

C. A and C are correct

D. None of the Above

Solutions:

Hence none of the above is correct answer.

We know that work done W = F.s where F is force and s is displacement.

If force acting on an object without causing any displacement, then it cannot define work done.

If object is displaced there is ambiguity whether it is displaced in the direction of force or not hence it cannot define work done.

A force is acting on the object we do not know whether the work done is same in the direction of force.


35. Which of the following illustrates Newton’s third law of motion?

A. When a bus starts suddenly, the passengers receive a backward jerk.

B. While catching a fast-moving cricket ball, the fielder gradually pulls his hand backwards with the moving ball.

C. The launching of a rocket.

D. When we stop pedalling, the bicycle slows down.

Solutions

When we stop pedalling, the bicycle slows down due to the frictional force acting on the bicycle.

The launching of a rocket illustrates Newton’s third law of motion.

Newton’s Third Law of Motion states that ‘To every action, there is an equal and opposite reaction’.

When the rocket is ignited, it releases gases from its thrusters thereby creating a force that will push rocket upwards.

A fielder pulling his hand back while catching a ball is an application of Newton’s second law of motion.

Newton’s Second Law of motion states that the rate of change of momentum of an object is proportional to the applied force in the direction of the force. i.e. F=ma. Where F is the force applied, m is the mass of the body, and a is the acceleration produced.

When a bus starts suddenly, the passengers receive a backward jerk an application of Newton’s first law of motion.

Newton First law states that Every object remains in uniform motion in a straight line unless compelled to change its state by the action of an external force.

Solutions

Given:

Principal = Rs 1,60,000

Time = 2 years

Rate of interest = 10% p.a compounded semi-annually

Concept used:

Amount = P ×(1 + r/100)t

When compounded semi-annually, r’ = r/2 and t’ = 2 × t

Calculation:

⇒ Compounded amount when compounded semi annually = Principal{1 + (Rate/200)}(2 × time)

⇒ Compounded Amount = 160000{1 + (10/200)}(2 × 2) = 160000(21/20)4 = Rs. 194481

⇒ Compound Interest = Amount – Principal = Rs. (194481 – 160000) = Rs. 34481

∴ Compound interest is Rs 34481.

50.A force increases the speed of a 1.0 kg object from 4 m/s to 8 m/s. The work done by the force will be ______.

A. 8 J

B. 32 J

C. 24 J

D. 16 J

Solutions

  • Mass of the Object (m) = 1 kg
  • Initial velocity of the object (u) = 4m/s
  • Final velocity of the object (v) = 8m/s
  • Total net work is done W (net) = Kinetic energy (During final velocity) – Kinetic Energy (During Initial Velocity).
  • Now by substituting the values in the above equation, we get

W(net) = ½ mv2 – ½ mu2

= ½ (1) (8)2 – ½ (1) (4)2

= 32 – 8

24 Joules.

Therefore, the total work done by the force is 24 J.


51.As long as an unbalanced force is applied to a body, there is a continuous change in its:

A. Weight

B. mass

C. speed

D. shape

Solutions

  1. As long as an unbalanced force is applied to a body, there is a continuous change in its speed.
  2. .Newton’s Second Law of motion states that the rate of change of momentum of an object is proportional to the applied force in the direction of the force. i.e. F=ma. Where F is the force applied, m is the mass of the body, and a is the acceleration produced.
  3. As the rate of change of speed is acceleration and hence, when an unbalanced force acts on an object it speeds changes accordingly.

56.A TV set is being sold for Rs. X in Delhi. A dealer went to Chandigarh and bought the TV at 20% discount (from the price of Delhi). He spends Rs. 600 on transport. Thus, he sold the set in Delhi for Rs. X making (100/7) % profit what is the value of X?

A. Rs. 7200

B. Rs. 8000

C. Rs. 8800

D. Rs. 9600

Solutions

Given :

A TV  set selling price in Delhi = Rs. X 

The discount is given on TV set in Chandigarh = 20%

Profit % = 100/7% = 

Transportation cost = Rs. 600

Formula Used:

Selling price = Cost Price × (100 + P%)/100

Calculation:

CP = 80% of X = 0.8X

According to the question

⇒ X = [0.8X + 600 (100 + 100/7)]/100

⇒ X = [(0.8X + 600)(800/7)]/100

⇒ 100X = [(0.8X + 600)(800)]/7

⇒ 700X = (0.8X + 600)(800)

⇒ 700X = 640X + 48000

⇒ 60X = 48000

⇒ X = 8000

∴ The value of X is Rs.8000

Alternate Method

⇒ Selling Price of TV in Chandigarh = X – 20% of X = Rs. 0.8X

⇒ Total cost price of TV in Delhi = 0.8X + 600

⇒ Selling Price = Rs. X

⇒ Profit% = {(X – 0.8X – 600)/(0.8X + 600)} × 100

⇒ 100/7 = {(0.2X – 600) / (0.8x + 600)} × 100

⇒ 0.8X + 600 = 1.4X – 4200

⇒ X = 8000

94. Generally, the valency of electropositive elements is ________.

A. 2, 1, 0

B. 4, 3, 2

C. 1, 2, 3

D. 0, 1, 2

Solutions

The general valency of electropositive elements is 1, 2, 3.

Atoms which tend to donate electrons and converts into a positive ion (M+) are called Electropositive atoms.

The atoms which have 1, 2, or 3 electrons in their valence shells will lose their electrons to attain a stable electronic configuration.

Some examples are Sodium, Magnesium, and Aluminum. These 3 elements will lose electrons to attain the configuration of the noble gas Neon.

96.Refer to the given figure and answer the question that follows.

If AB is parallel to EC and ∠BCD = 72°, then, what is the value of ∠ABC?

A. 75°

B. 73°

C. 72°

D. 67°

Solutions

Given:

∠BCD = 72°

AB is parallel to EC

Concept used:

When two lines are parallel to each other, alternate interior angles are equal.

Calculation:

Since AB is parallel to EC, alternate interior angles are = ∠ABC = ∠BCD

By alternate angle theorem,

⇒ ∠ABC = ∠BCD = 72°


97. A type of reproduction in which a part of a plant body develops into a new individual is called _________.

A. fission

B. regeneration

C. vegetative propagation

D. sexual propagation

Solutions

  • Vegetative reproduction is the type of reproduction in which a part of a plant body develops into a new individual. 
  • Vegetative propagation is a type of asexual reproduction in which new plants are produced from roots, stems, leaves and buds.
  • As new offspring comes from the vegetative part of the plant, hence the name Vegetative propagation.
TypeDefinition
 FissionIt is a type of asexual reproduction in which a single cell divides into two or more cells
 RegenerationIt is a type of asexual reproduction. It is the ability of a simple organism to re-grow its lost parts.
 Sexual   PropagationGenes of two different parent cell come together to form a new individual.

99.Two inlet pipes, A and B, can fill an empty cistern in 22 and 33 hours, respectively. They were opened at the same time, but pipe A had to be closed 3 hours before the cistern was full. How many hours in total did it take the two pipes to fill the cistern?

A. 15

B. 16.2

C. 14.2

D. 16

Solutions

Let the cistern be filled in x hours

⇒ Efficiency of Pipe A = 1/22

⇒ Efficiency of pipe B = 1/33

According to question,

⇒ {(x – 3)/22} + (x/33) = 1

⇒ (3x – 9 + 2x)/66 = 1

⇒ 5x – 9 = 66

⇒ x = 15

∴ Cistern gets filled in 15 hours.

Shortcut Trick

A alone can fill it in 22 hours

B alone can fill it in 33 hours

Total work = LCM of (22, 33) = 66 unit

As in question it is given that A will leave the work 3 hours before so if A doesn’t leave then they will complete the total work = 66 + 3 × 3 = 75 unit

∴ Time taken = 75/(3 + 2) = 15 hours


100. What will be the direction of the magnetic field at a point directly below a horizontal power line with the current flowing from east to west when viewed from the west end?

A. Anticlockwise

B. Clockwise

C. Parallel to the flow of the current

D. Perpendicular to the flow of the current

Solutions

Anticlockwise will be the direction of the magnetic field at a point directly below a horizontal power line with the current flowing from east to west when viewed from the west end.

According to ampere’s right-hand thumb rule when a current carrying conductor is placed in the right hand with thumb showing the direction of current and all other fingers are enclosed around the conductor will show the direction of the magnetic field.

When we place our hand on a conductor that is flowing with the current in the east to the west direction the enclosed fingers show the anti-clockwise direction of current when viewed from the west.
