1. 6 years ago, a mother’s age was 6 times her daughter’s age. Three years hence, the daughter will be one-third her mother’s age. The current age (in years) of the mother is:
A. 45
B. 39
C. 36
D. 42
Solutions
Let the age of daughter before 6 years be x
Mother’s age before 6 years = 6x
Hence after 9 years, daughter’s age = (x + 9) year
Mother’s age after 9 year = (6x + 9) year
According to the question,
⇒ (x + 9) = (6x + 9)/3
⇒ 3x + 27 = 6x + 9
⇒ 3x = 18
⇒ x = 6 year
⇒ Present age of mother = (6x + 6) ⇒ (6 × 6 + 6)
⇒ 42 years

A. zero
B. = P.E.
C. < P.E.
D. > P.E.
Solutions
CONCEPT:
- Law of the Conservation of energy: “Energy can neither be created nor be destroyed. It just gets transfers in one form to another.“
- Total energy (TE): The sum of the potential energy (PE) and kinetic energy (KE) is called total energy.
TE = KE + PE
- Potential Energy: The stored energy of a body by the virtue of its position is called potential energy.
- Example: A rock sitting at the edge of a cliff has potential energy.
PE = m g h
Where m is mass, g is the acceleration due to gravity and h is the height
- Kinetic Energy: The energy possessed by the body by virtue of being in motion is called kinetic energy.
KE = 1/2 m V2 where V is the velocity of the body.
- Example: A ball thrown would have kinetic energy.
EXPLANATION:
- According to the energy conservation principle, the sum of the kinetic energy and potential energy of the body always remains constant.
- As the body comes down the height of the body decreases and hence the potential energy decreases. If the potential energy decreases the kinetic energy will increase.
- As soon as the body touches the ground, all the initial potential energy of the particle gets converted into kinetic energy.
- The potential energy (P.E) of a body at a certain height is 200 J. The kinetic energy possessed by it when it just touches the surface of the earth is the same as the Potential Energy (= P.E.). So the option 2 is correct.

A. 8
B. 24
C. 168
D. 192
Solutions
We know that the number is divisible by 4 if the last two digits are divisible by 4.
Let the number be _ _ _ _ _
If the tens place (second digit from the right) is filled by 4 , then out of 4,5,6,7,8,9 only 8 can be in units place (Last Digit from right) as 48 are divisible by 4 , the remaining 3 places can be filled from other 4 digits in 4P3 = 4!/(4–3)! = 24 . So, with digit 4 in tens place we can have 24*1 = 24 numbers.
If the tens place is filled by 5, then the units place has to be only 6 and the other 3 places can be filled from other 4 digits, so we have 4P3 *1 = 24 numbers.
If the tens place is filled with 6 then we can have 4 or 8 in the unit’s place and other 3 places can be filled in 24 ways so here we have 24*2 = 48 numbers
If the tens place is filled with 7 then the units place has to be only 6 which is divided by 4 as 76 is divisible 4 and the other 3 places can be filled from other 4 digits, so we have 4P3 *1 = 24 numbers.
If the tens place is filled with 8 then the units place has to be only 4 which is divided by 4 as 84 is divisible 4 and the other 3 places can be filled from other 4 digits, so we have 4P3 *1 = 24 numbers
Similarly, if the tens place is filled by 9 then the units place has to be only 6 which is divided by 4 as 96 is divisible 4 and the other 3 places can be filled from other 4 digits so we have 4P3 *1 = 24 numbers
So, the total value of n is 24 + 24 + 48 + 24 + 24 + 24 = 168

44. A body of mass 100 gm is rotating on a circular path of radius r with constant velocity. The work done in one complete revolution will be:
A. zero
B. (100/r) J
C. 100 r J
D. (r/100) J
Solutions
CONCEPT:
- Circular Motion: The movement of an object along a circumference of a circle or rotation along a circular path is called circular motion.
- Uniform circular motion: The circular motion in which the speed of the particle remains constant is called uniform circular motion. In a uniform circular motion, force supplies the centripetalacceleration.
- The kinetic energy and the speed of the body remain constant.
If the Force F acts on a body and it gets displaced by a displacement of S, the work done in that case is given by:
Work done (W) = FS Cos θ
- Centripetal Force: It is a force required to move a body uniformly in a circle. This force acts along the radius and towards the center of the circle.
- The centripetal force required for circular motion along the surface of the road, towards the center of the turn. The Static friction between tire and road provides the necessary centripetal force.
CALCULATION:
It is given that,
Mass = 100 gm, radius = r
- Now, here, please note that the movement is uniform circular in motion. The angle between centripetal force and displacement is 90°. The force and displacement are perpendicular to each other
⇒ cos 90° = 0
Work done (W) = FS Cos 90° = 0 J
- So, no matter what is the mass, radius, or velocity, the work done would be zero.
- Hence, the work done in one complete revolution is Zero Joule. So option 1 is correct.

47. If the direction of applied force and direction, in which an object moves, are perpendicular to each other, then ________.
A. Positive work is done
B. No power is released
C. No energy is released
D. No work is done
Solutions
The correct answer is option 4 i.e No work is done
Force: It is defined as the push/pull which is required to change the state of the object.
Work: It is the amount of force required to move an object.
Work = Force × Displacement
- If the direction of applied force and direction, in which an object moves, are perpendicular to each other, then the work is done = 0 i.e no work is done.
- Work is done only when a certain force is applied on an object and the object moves a certain distance on the direction of the applied force. Hence work done is zero when the direction is perpendicular.
48. An object moving with a deceleration of 2.5 ms-2 comes to rest after 20 s. What is its initial velocity?
A. 20 ms1
B. 50 ms-1
C. 0 ms-1
D. 10 ms-1
Solutions
The correct answer is 50 ms-1.
Explanation:
In the equation of motion v = u + at, ‘u’ represents the initial velocity of the body under consideration. ‘v’ represents final velocity, ‘a’ represents the acceleration, and ‘t’ represents the total time taken. This is the equation of motion.
⇒ t = 20 s
⇒ It is stated that the body comes to rest: V = 0 ms-1
⇒ v = u + at
⇒ 0 = u + (-2.5) x 20 [deceleration = – 2.5]
⇒ u = 50 ms-1
⇒ The initial velocity = 50 ms-1 as given in the question.

A. 35
B. 17
C. 24
D. 15
Solutions
Given,
Builder build a wall in 10 hours
Wall built in 1 hour = 1/10 of the total work
Destroyer destroy the wall in 14 hours
Wall destroyed by destroyer in 1 hour = 1/14
Total work done by builder and destroyer in 1 hour = (1/10 – 1/14) = 1/35
As, they work for 7 hours
Work done by both builder and destroyer in 7 days = (1/35) × 7 = 1/5
Remaining work = 1-(1/5) = 4/5
According to question, after 7 days destroyer was taken out therefore remaining work will be done by the builder
Time taken by the builder for remaining wall = (4/5)/(1/10) = (4/5) × 10 = 8 hour
Total time to build the wall = (7 + 8) = 15 hour

One student left the group as a result of which the average of the remaining students rose to 29.5 Afterwards, another student came in as a result of which the average marks of the group dropped to 28.8 What is the average of the combined marks obtained by the students who left and the one who joined?
A. 14
B. 14.5
C. 15
D. 13.5
Solutions
Given,
Average marks of 25 students = 29
As we know,
Total marks obtained by students = average marks obtained by student × total no.of students
Average of marks obtained by two students = (marks obtained by left student + marks obtained student who came)/2
CALCULATION:
Total marks obtained by 25 students = 25 × 29 = 725
According to the question,
One student left the group as a result of which the average of the remaining students rose to 29.5
Total marks obtained by 24 students = 24 × 29.5 = 708
Marks obtained by left student = 725 – 708 = 17
According to the question,
Another student came in as a result of which the average marks of the group dropped to 28.8
Therefore,
Total marks obtained by the students after another student came = 25 × 28.8 = 720
⇒ Marks obtained by student who came = 720 – 708 = 12
The average of the combined marks obtained by the student who left and the one who joined
⇒ (17 + 12)/2
⇒ 14.5
74. Magnitude of displacement from initial position to final position is a ________.
A. Curved line

A. Dowry
B. Divorce
C. Same sex marriages
D. Domestic Violence
Solutions
The correct answer is option 3 i.e Same-sex marriages
- Section 377 of the Indian Penal Code (IPC) is an act that criminalises homosexuality and was introduced in the year 1861 during the British rule of India.
- Section 377 refers to ‘unnatural offences’ and says whoever voluntarily has carnal intercourse against the order of nature with any man, woman or animal, shall be punished with imprisonment for life, or with imprisonment of either description for a term which may extend to 10 years, and shall also be liable to pay a fine.
Why in news:
- The Supreme Court of India on September 6, 2018, decriminalised Section 377 of the IPC and allowed gay sex among consenting adults in private.
- The SC ruled that consensual adult gay sex is not a crime affirming that sexual orientation is natural and people have no voluntary control over it.
76. Inlet Pipe A can fill can cistern is 35 hours while outlet Pipe B can drain the filled cistern in 40 hours. The two pipes are opened together when the cistern is empty, but the outlet pipe is closed when the cistern is three-fifths full. How many hours did it take in all to fill the cistern?
A. 185
B. 182
C. 184
D. 180
Solutions
Given,
Inlet Pipe A can fill can cistern is 35 hours,
Therefore, A fill the tank in 1 hour = 1/35
B empty the tank in 1 hour = 1/40
A and B can fill the tank in 1 hour = (1/35) – (1/40) = 1/280
Let the two pipes are opened together for X hour till the cistern is three-fifths full
Therefore,
A and B together can fill the tank in X hour = X/280
⇒ X/280 = 3/5
⇒ X = 168 hour.
Now according to the question,
The outlet pipe is closed when the cistern is three-fifths full.
Therefore, remaining part (1 – 3/5) = 2/5 of the tank will be filled by the inlet pipe A,
Time taken by the inlet pipe to fill the remaining tank = (2/5)/ (1/35) = (2/5) × 35 = 14 hour.
Therefore, the total time to fill the tank = (168 + 14) = 182 hours.

96. We all know from our observation that water can exist in three states of matter.
Statements:
a. Solid, as ice
b. Liquid, as petrol and
c. Gas as O2
Which of the following statements is/are true?
A. Only A is true, B and C are false
B. A and B are true, C is false
C. All are false
D. All are true
Solutions
The correct answer is Only A is true, B and C are false.
Key Points
- Water can exist in three states of matter as solid, liquid, and gas.
Solid water:
- When water freezes, its molecules move farther apart, making ice less dense than water.
- Hence, ice is lighter than the same volume of water, and so ice will float in water. Water freezes at 0°C, 32° F.
- Ice, snow, and frost are examples of water in the solid-state. Liquid water freezes at 0 degrees Celsius.
- Celsius is a scale that measures temperature.
- It is possible to solidify water without allowing it to crystallize.
- This has been demonstrated in laboratory conditions decades ago, using metal plates chilled with dry ice or liquid nitrogen and slamming them together to trap a falling water drop between.
Liquid water:
- It is the most familiar form of water which we use in drinking, bathing, washing clothes, etc.
- Clouds, snow, and rain are all made up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water.
- The equation for the formation of liquid water is: 2H2(g)+O2(g)→2H2O(l) 2 H 2 ( g ) + O 2 ( g ) → 2 H 2 O ( l ) .
Gaseous water:
- Water vapors and steam are the gaseous forms of liquid.
- Steam is formed at 100°C, 212°F.
- Water existing as gas is called water vapor.
- When referring to the amount of moisture in the air, we are actually referring to the amount of water vapor.
