8. The volume of a right circular cone, whose radius of the base is the same as five-ninths of its altitude and the volume of a sphere are equal. The ratio of the radii of the cone to the sphere is:

B. 1 : 1

Solutions

Right circular cone:

Altitude = h and radius = r

Given, radius of the base is the same as five-ninths of its altitude:

∴ r = 5h/9

⇒ h = 9r/5

Volume of a right circular cone = π/3 × r² × h

= π/3 × r² × 9r/5

= 3π/5 × r³

And

Volume of sphere of radius R = 4π/3 × R³

Since the volumes of two figures are equal:

3π/5 × r³= 4π/3 × R³

⇒ r³/R³= 20/9

⇒ r³/R³= 60/27

⇒ r : R =

21. You are given a question and two statements. Identify which of the statements is/are necessary/sufficient to answer the question.

What will be the age of S, 3 years from now?

Statements:

1. M is 25 years old today

2. S is younger to M by 10 years

A. Statement 2 alone is sufficient

B. Statement 1 alone is sufficient

C. statement 1 and 2 together are not sufficient

D. statements 1 and 2 together are necessary

Solutions

1. M is 25 years old today.

Here, there is no reference to S.

Therefore, Statement 1 alone is not sufficient.

2. S is younger to M by 10 years

Here, we need to know the age of M to deduce the age of S.

Therefore, Statement 2 alone is not sufficient.

Combining 1 and 2, we get:

S = M – 10 and M = 25 years.

So, S’s age = 25 – 10 = 15 years.

So, both 1 and 2 statements are required to answer the question.

Hence, ‘statements 1 and 2 together are necessary’ is the correct answer.

22. Which of the following numbers will have an irrational square root?

K, F, M and T are standing in a queue. Based on the following information, can we tell who is standing in the second place if we arrange shortest to tallest?

Statements:

1. F is the tallest.

2. K is taller than T.

3. T is the shortest.

A. statements 1 and 2 together are sufficient.

B. statement 1 and 3 are sufficient to solve.

C. The statements are insufficient.

D. Statements 1, 2, 3 alone are enough to solve.

Solutions

Combining statements 1 and 3, we can arrange in the shortest to tallest order”

T < _ < _ < F

Remaining- K and M

Since there is no given relationship between K and M, we get two cases:

Case 1:

T < K < M < F

Case 2:

T < M < K < F

Thus, there is no way of concluding who is standing in the second place if we arrange shortest to tallest. Hence, the statements are insufficient.

Hence, ‘The statements are insufficient’ is the correct answer.

24. In a bag the ratio of red balls to green balls is 15 : 26. If 12 more green balls are added to the bag the ratio of red balls to green balls will become 1 : 2. How many red balls are there in the bag?

A. 30

B. 45

C. 15

D. 60

Solutions

Let the number of red balls be 15x

Let the number of green balls be 26x

When 12 more green balls are added, the number of green balls become = 26x + 12

The new ratio of red balls to green balls = 1 : 2

15x/26x+12=1/2

2 × 15x = 1 × (26x + 12)

30x = 26x + 12

30x – 26x = 12

4x = 12

x = 3

Therefore, the number of red balls in the bag = 15x = 15 × 3 = 45

Hence, ‘45’ is the correct answer.

31. If 2x² + ax + 2b, when divided by x – 1, leaves a remainder of 16 and x² + bx + 2a, when divided by x + 1, leaves a remainder of -1 then a + b equals:

A. 14

B. -8

C. -14

D. 8

Solutions

If 2x² + ax + 2b, when divided by x – 1, leaves a remainder of 16.

Putting (x = 1) in the equation 2x² + ax + 2b, it will be equal to 16

⇒ 2 + a + 2b = 16

⇒ a + 2b = 14 —- (1)

And

x² + bx + 2a, when divided by x + 1, leaves a remainder of -1.

Putting (x = -1) in the equation x² + bx + 2a, it will be equal to -1;

⇒ 1 – b + 2a = -1

⇒ 2a – b = -2 —- (2)

Multiply equation 2 by 2 and add in equation 1:

⇒ 5a = 10

⇒ a = 2

And from equation 1:

b = 6

Hence,

(a + b) = 2 + 6 = 8

D. 50, 150 and 75

Solutions

A and B can complete a task in 50 days, B and C can complete it in 37.5 days while C and A can do the same task together in 30 days.

Suppose Efficiencies of A, B and C are a, b and c respectively;

Suppose total work = 150 units (LCM of 50, 37.5 and 30)

So,

a + b = 150/50 = 3 units

b + c = 150/37.5 = 4 units

c + a = 150/30 = 5 units

Adding all three:

(a + b + c) = (3 + 4 + 5)/2 = 6 units

Hence,

c = 6 – 3 = 3 units

a = 6 – 4 = 2 units

b = 6 – 5 = 1 units

Now,

Time in which A can complete the task alone = 150/2 = 75 days

Time in which A can complete the task alone = 150/1 = 150 days

Time in which A can complete the task alone = 150/3 = 50 days

46. A boy is observing a hot air balloon flying at 692 m above ground. The angle of elevation of balloon from the eyes of the boy was 60°. After sometime, the balloon moves away horizontally from the boy and the angle reduces to 30°. What is the approximate distance travelled by the balloon? Take 3=1.73

A. 400 m

B. 800 m

C. 600 m

D. 200 m

Solutions

In the figure:

The balloon was at point D when angle of elevation was 60° i.e. ∠BAD = 60°

And

After some time, the balloon was at point E when angle of elevation was 30° i.e. ∠CAE = 30°

BD = CE = 692 m (Height at which the balloon is flying)

Now in triangle ABD:

Tan BAD = BD/AB

⇒ Tan 60° = 692/AB

⇒ AB = 692/3

⇒ AB = 692/1.73 = 400 m

Now in triangle EAC:

Tan CAE = EC/AC

⇒ Tan 30 = 692/AC

⇒ AC = 692 × 3

⇒ AC = 692 × 1.73 = 1197.16 m

Hence,

Distance travelled by the balloon = ED = BC = AC – AB

= 1197.16 – 400

= 797.16 ≈ 800 m

Number will be between 60 and 70 whose square has last digit 6.

Possible numbers = 64 and 66

But 65² = 4225

∴ 64 can’t be the answer as it will be more than 65.

∴ Square root of 4356 = 66

Alternate method

We can find the right option by simply squaring each option

84² = 7056

66² = 4356

64² = 4096

76² = 5776

Hence, option 2 is correct.

84. Consider the given statement(s) and decide which of the given assumptions is/are implicit in the statement.

Statement: “We are all victims of our thoughts,” says a title in a newspaper column.

Assumptions:

I. Our actions are based on our thoughts.

II. Newspapers are the best source of information.

A. Both I and II are implicit

B. Only assumption II is implicit

C. Neither I nor II is implicit

D. Only assumption I is implicit

Solutions

The statement does not talk or suggest anything about the newspaper in general.

Therefore, assumption II is not implicit.

The meaning of the title is that our sufferings are a product of our thoughts.

Thus, it can be safely assumed that our actions depend on our thoughts.

Hence, only assumption I is implicit.

85. The effect of Thrust depends on which of the following?

A. Area

B. Volume

C. Mass

D. Weight

Solutions

CONCEPT:

Thrust: The force acting perpendicular to the surface of the object is called thrust.
- It is a type of force so the SI unit of thrust is Newton (N).
- The effect of thrust is more on the smaller surface area than the thrust acting on a larger surface area.

EXPLANATION:

The effect of thrust depends on the area of the surface on which it acts. So option 1 is correct.

The normal force exerted by liquid at rest on a given surface in contact with it is called the thrust of liquid on that surface.
The normal force (or thrust) exerted by liquid at rest per unit area of the surface in contact with it, is called pressure of liquid or hydrostatic pressure.

87. A student has to secure 40% marks to pass. He obtains 40 marks and fails by 40 marks. What are the maximum marks obtainable?

A. 400

B. 250

C. 200

D. 500

Solutions

Given:

Pass mark = 40%

The student gets 40 marks and failed by 40 numbers

Calculation:

Suppose the maximum marks = x

A student has to secure 40% marks to pass i.e. ‘0.4x’ marks.

He obtains 40 marks and fails by 40 marks.

So,

40 + 40 = 0.4x

⇒ 0.4x = 80

⇒ x = 80 × (10/4) = 200

∴ The maximum obtainable marks are 200.

Shortcut Trick

The student get 40 marks and failed by 40 marks

⇒ Passing mark = (40 + 40) = 80

Accordingly,

40% → 80

⇒ 100% → (80/40) × 100 = 200

∴ The maximum obtainable marks are 200.

88. Pipe A can fill an empty cistern in 6.8 hours. Pipe B can fill it up in 10.2 hours. Only Pipe B is turned on for 1.7 hours after which Pipe A is also tuned on. How much time will it take in all to fill up the cistern?

A. 5 hours 6 minutes

B. 5 hours 12 minutes

C. 5 hours 5 minutes

D. 5 hours 10 minutes

Solutions

Pipe A can fill an empty cistern in 6.8 hours and pipe B can fill it up in 10.2 hours.

Suppose the capacity of cistern = 20.4 units (LCM of 6.8 and 10.2)

Hence,

Efficiency of pipe A = 20.4/6.8 = 3 units

Efficiency of pipe B = 20.4/10.2 = 2 units

Given: Only Pipe B is turned on for 1.7 hours after which Pipe A is also tuned on.

Suppose the cistern got filled in ‘a’ hours;

So, Pipe B was operated for complete ‘a’ hours while pipe A was operated for (a – 1.7) hours;

(a – 1.7) × 3 + a × 2 = 20.4

⇒ 3a – 5.1 + 2a = 20.4

⇒ 5a = 25.5

⇒ a = 5.1 hours or 5 hours 6 minutes

Hence, time to fill up the cistern = 5 hours 6 minutes

A. 80 km/h

B. 70 km/h

C. 75 km/h

D. 85 km/h

Solutions

Total distance covered by train = length of train + length of bridge

= 153 + 747 = 900 m

Time = 40.5 seconds

So,

Speed of train = 900/40.5 m/sec

Converting m/sec into km/hr ⇒ (900/40.5) × (18/5) = 180/2.25 = 80 km/hr

The logic is:

Word	J	A	I	L
Code(Only unit digit is considered)	10 – 1 = 9	1 – 1 = 0	9 – 1 = 8	12 – 1 = (1)1

Similarly,

Word	P	R	I	S	O	N
Code(Only unit digit is considered)	16 – 1 = (1)5	18 – 1 = (1)7	9 – 1 = 8	19 – 1 = (1)8	15 – 1 = (1)4	14 – 1 = (1)3

Hence, ‘578843’ is the correct answer.

92. Which pattern will the given transparent sheet resemble when it is folded at the dotted line?

A. C

B. D

C. B

D. A

Solutions

Let us observe the pattern of figures A and C.

The smaller end of the figure will always be in touch with the folded line as is in the original figure. This condition is not followed by figures A and C. Thus, they will be eliminated.

Let us observe the pattern of figure D.

Only one end of the figure will always remain in touch with the folded line as is in the original figure. Thus, figure D will be eliminated.

Hence, ‘figure B’ is the correct answer

93. If ∠BCD = 82°, then ∠BAC = ?

A. 85°

B. 82°

C. 83°

D. 77°

Solutions

Given: ∠BCD = 82°

From the Alternate segment theorem:

In any circle, the angle between a chord and a tangent through one of the end points of the chord is equal to the angle in the alternate segment.

Hence, ∠BAC = ∠BCD = 82°

94. A ball thrown up vertically returns to the ground after 12.5 second. Find the velocity with which it was thrown up? (g = 10 ms^-2)

A. 62.5 ms^-1

B. 65 ms^-1

C. 12.5 ms^-1

D. 10 ms^-1

Solutions

CONCEPT:

Equation of motion: The mathematical equations used to find the final velocity, displacements, time, etc of a moving object without considering force acting on it are called equations of motion.
These equations are only valid when the acceleration of the body is constant and they move on a straight line.

There are three equations of motion:

V = u + at

V2 = u2 + 2 a S

Where, V = final velocity, u = initial velocity, s = distance traveled by the body under motion, a = acceleration of body under motion, and t = time taken by the body under motion.

EXPLANATION:

Here acceleration is acceleration due to gravity ( a = g = 10 m/s2).

Time of ascent (t) = Time of descent (t)= 12.5/2 = 6.25 s

Final velocity (v) = 0 (at maximum height) , Initial velocity (u) = ?

Using v = u + at,

we get

⇒ 0 = u + (-10 x 6.25)

⇒ -u = – 10 x 6.25

⇒ u = 62.5 ms^-1

The Velocity with which it was thrown up is 62.5 ms-1. So option 1 is correct.

Conclusions:

I. Ranjan is a civil contractor

II. Lata is fond of houses

A. Conclusion I alone follows

B. Neither I nor II follows

C. Both the conclusions follow

D. Conclusion II alone follows

Solutions

The information in the statement is insufficient to determine the profession of Ranjan.

Therefore, conclusion I does not follow.

The statement does not give any information about the likes or dislikes of Lata.

Therefore, conclusion II does not follow.

Hence, “neither I nor II follows” is the correct answer.

98. The momentum of a body of mass 200g with kinetic energy of 10 J is ________.

A. 3 kg m/s

B. 2 kg m/s

C. 5 kg m/s

D. 0.33 kg m/s

Solutions

CONCEPT:

Momentum: momentum is the productof the mass and velocity of an object. It is a vectorquantity, possessing a magnitude and a direction.
- The unit of momentum (P) is kg m/s.
- Dimension: [MLT^-1]

⇒ Momentum (P) = M V

Where M = mass, V = velocity.

Kinetic energy: It is the energy of the body associates with its motion.
- The unit of kinetic energy (K) is kg m s^-2.
- Dimension: [ML²T^-2]

⇒ K = ½ m v2

where K is kinetic energy, m is mass; v is the velocity of the body.

CALCULATION:

Given Mass (M) = 200gm = 0.2 kg.

⇒ Kinetic energy = 10 J

⇒ (1/2)MV² = 10 J

⇒ (1/2) x 0.2 x V²= 10

⇒ V² = (10×2)/0.2

⇒ V² = 100

⇒ V = 10 ms^-1

Momentum = M V

= 0.2 x 10

Momentum = 2 kg m/s.

The Correct Answer is Option 2 i.e 2 kg m/s.

99. n = number of times the wheel of a bus will rotate to cover a distance of 99 km. if the diameter of the wheel is 63 cm, then find the value of n.

A. 45,000

B. 35,000

C. 40,000

D. 50,000

Solutions

Diameter of the wheel = 2r = 63 cm

So, circumference of the wheel = 2πr = 63π cm = 63 × 22/7 = 198 cm

Distance = 99 km = 99 × 10⁵cm

Hence,

Number of revolutions

= (99 × 10⁵)/198

= 10⁵/2

= 100000/2

= 50000

100. Two men X and Y walk from P to Q a distance of 21 km at 3 and 4 km an hour respectively. Y reaches Q returns immediately and meets X at R, the distance from P to R is

A. 18 km

B. 17 km

C. 16 km

D. 17.5 km

Solutions

Given:

Speed of X = 3 km/hr

Speed of Y = 4 km/hr

So,

Time in which Y will reach Q from P = 21/4 hr

Distance covered by X in 21/4 hrs = 3 × 21/4 = 63/4 km

∴ Distance between X and Y = 21 – 63/4 = 21/4 km

Now when Y reached Q and started towards P, relative speed of X and Y = 4 + 3 = 7 km/hr

∴ Time in which 21/4 km will by both (After which they will meet) = (21/4)/7 = 3/4 hours

Distance of R from Q = Distance travelled by Y in 3/4 hours = 3/4 × 4 = 3 km

So,

Distance of R from P = 21 – 3 = 18 km
