Answers
1. Answer: a
Explanation:
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

CONCEPT:
Sound: A local disturbance whose propagation is facilitated by the collisions
between particles this disturbance propagates in a longitudinal wave, imagine
one molecule hitting the next molecule, and then that molecule hitting the next,
and so forth.
It is a mechanical wave that needs a medium to travel.
The speed of sound is maximum in solid then it is in liquid and slowest in
gases.
Speed of sound: The distance traveled per unit time by sound waves as it
propagates through an elastic medium.
The velocity of sound in a gaseous medium is given by:
Where P = pressure, ρ = density, and γ = ratio of two principal specific heats of the
gas
The speed of sound remains almost the same for all frequencies in a given
medium under the same physical conditions.
A state of matter is one of the distinct forms in which matter can exist.
The four fundamental states of matters are - solids, liquids, gases, and
plasma .

Work done:
Work is said to be done when a force applied on the body displaces the
body through a certain distance in the direction of a force.
Where F = force, s = distance, and cos θ = angle between F and s.
The SI unit of work done is N-m or Joule (J) .
Work done (W) = F ⋅ s cos θ = Fs cosθ
Key Points
Work is done whenever the given condition is satisfied:
(i) A force should act on an object
(ii) There is a displacement of the body caused by the applied force along the
direction of the applied force.
Explanation:
Here,
1. A force has acted on an object without causing any displacement of it. -
Doesn't satisfy the condition.
2. Only when an object is displaced. - Doesn't satisfy the condition.
3. Only when force has acted on the object. - Doesn't satisfy the condition.
4. Any of the above - Doesn't satisfy the condition.
So the correct option is b & c
It will only be true when force is applied and displacement is in the direction of the
force.

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.

Formula Used:
Working Efficiency = (Work Done)/(Time taken)
⇒ Efficiency of Rohan = 1/15
⇒ Efficiency of Rohit + Efficiency of Rohan = 1/10
⇒ Efficiency of Rohit = (1/10) – (1/15) = 1/30
∴ Rohit alone can do the same job in 30 days
48. Answer: b
Explanation:
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,
Rate becomes half i.e R = 10%/2 = 5%
And time becomes double
New time T = 2 × 2 = 4 years
Calculation:
Now, According to the formula used
A = P × (1 + R/100)
T
⇒ A = 1,60,000 (1 + 5/100)
4
⇒ A = 194481
So, Compount Interest = Amount - Principal
⇒ Compount Interest = 194481 - 160000
⇒ Compount Interest = 34,481
∴ The required compound interest is Rs. 34481.

50. Answer: c
Explanation:
CONCEPT:
Work-energy theorem: It states that the sum of work done by all the forces
acting on a body is equal to the change in the kinetic energy of the body i.e.,
Work done by all the forces = K f - K i
Where v = final velocity, u = initial velocity and m = mass of the body
EXPLANATION:
Given that:
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).
W = 2
1mv
2 − 2
1mu
2 = ΔK
Now by substituting the values in the above equation, we get
W (net) = ½ mv
2– ½ mu
2
= ½ (1)×(8)
2– ½ (1)×(4)
2
= 32 - 8 Joule
=24 Joules.
Therefore, the total work done by the force is 24 J.
51. Answer: c
Explanation:
As long as an unbalanced force is applied to a body, there is a continuous
change in itsspeed.
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.
As the rate of change of speed is acceleration and hence, when an unbalanced
force acts on an object it speeds changes accordingly.

The discount is given on TV set in Chandigarh = 20%
Profit % = 100/7% = %
Transportation cost = Rs. 600
147
2
Formula Used:
Selling price = Cost Price × (100 + P%)/100
Calculation:
CP = 80% of X = 0.8X
According to the question
⇒ X =
⇒ X =
⇒ 100X =
⇒ 700X = (0.8X + 600)(800)
⇒ 700X = 640X + 48000
⇒ 60X = 48000
⇒ X = 8000
∴ The value of X is Rs.8000
⇒ 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

Simple Year Leap Year
365 ÷ 7 = 52 weeks + 1 odd
day
366 ÷ 7 = 52 weeks + 2 odd
day
Years No. of odd days
100 years 5
200 years 3
300 years 1
400 years 0
Code for weekdays:
No. of odd days Day
0 Sunday
1 Monday
2 Tuesday
3 Wednesday
4 Thursday
5 Friday
6 Saturday
Note : Multiple of 400 years i.e. 800, 1200, 1600, 2000 have 0 odd days .
Calculating leap year: For Finding the number of leap year (1 - 99) years, divide the
number of years by 4 and the quotient will be the number of leap years.
We will find the day on 1st March 2005 = (2000 years + Period from 1.1.2005 to
1.3.2005)
As mentioned above:
Odd days in 1600 years = 0
Odd days in 400 years = 0
Number of leap years till 2004 = 1 (in 2004) = 2 odd days
Number of ordinary years till 2004 = 3 (2001, 2002, 2003) = 3 odd days
Now number of odd days in:
Jan, Feb, and March
(31 + 28 + 1) = 60 days = 4 odd days
Total number of odd days = (0 + 0 + 2 + 3 + 4) = 9 days = 2 odd days
Since 2is the code for Tuesday
So on 1st March, 2005 it was Tuesday.
Therefore, Friday = 1st March + 3 days = 4th March.
Friday will repeat after 7 days.
⇒ 4th March + 7 = 11th March.
Thus, in March, 2005 Friday falls on 4th, 11th, 18th and 25th.
Hence, the correct answer is "Option 3".

Given:
∠BCD = 72°
AB is parallel to EC
Concept used:
1) Alternate segment theorem:
According to this theorem, the angle formed between the tangent and the chord
through one of the end
points is equal to the measure of the angle opposite in the alternate segment.
Example of Alternate segment theorem:
In which DE is the tangent and BC is a chord.
∠BCE is made by the tangent and chord BC. This is equal to ∠BAC in the alternate
segment.
∠ACD is made by the tangent DE and chord AC. This is equal to ∠ABC in the
alternate segment.
2) Alternate interior angles:
Since, the given lines m and n are parallel, therefore the alternate interior angles will
be congruent.
∠1 = ∠2 and ∠3 = ∠4.
Calculation:
According to the question,
Since AB is parallel to EC, alternate interior angles are = ∠ABC = ∠BCD
By alternate angle theorem,
⇒ ∠ABC = ∠BCD = 72°
By using Alternate segment theorem,
⇒ ∠ABC = ∠ACE = 72°
By using Alternate interior angles theorem
⇒ ∠BAC = ∠ACE = 72°
∴ The required answer will be 72°.

99. Answer: a
Explanation:
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.
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
