A right circular cylinder of radius r cm and height h cm (h > 2r) just encloses a sphere of diameter:
A)
r cm
B)
h cm
C)
2h cm
D)
2r cm
A sphere that is just enclosed by a right circular cylinder must fit exactly inside the cylinder. Since the cylinder’s radius is r cm, its diameter is 2r cm. The largest possible sphere that can fit inside has diameter equal to the cylinder’s diameter, i.e. 2r cm. The condition h > 2r only ensures the height is enough; it does not change the sphere’s diameter. Therefore, the correct answer is 2r cm.
The World Health Organisation has decided to celebrate the year 2020 as which year?
A)
International year for malnutrition eradication
B)
International Year for campaign against obesity
C)
International Year to ensure access to life saving medicines
D)

The World Health Organization (WHO) declared 2020 as the 'Year of the Nurse and the Midwife' to recognize the vital role of nurses and midwives in healthcare. The other options are not official WHO designations for 2020.
A speed of 15 m/s is equal to:
A)
75 km/h
B)
54 km/h
C)
45 km/h
D)
60 km/h
To convert m/s to km/h, multiply by 18/5. So, 15 × 18/5 = 54 km/h. Therefore, the correct answer is 54 km/h. The other options are incorrect because they do not match the standard conversion.
In a cylinder, if radius is halved and height is doubled, the volume will be:
A)
same
B)
halved
C)
doubled
D)
four times
Volume of a cylinder is V = πr²h. If the radius is halved, r becomes r/2, so r² becomes r²/4. If the height is doubled, h becomes 2h. New volume = π × (r²/4) × 2h = (1/2)πr²h. So the volume becomes half of the original, i.e. halved. Therefore, option (b) is correct.
Human Rights Day is observed on which of the following day?
A)
5th December
B)
6th December
C)

A)
Increase in personal Income tax rate
B)
Raising the price of gasoline by the government
C)

The violent unrest in Iran that began in November 2019 was triggered by the government’s sudden increase in gasoline prices. This led to widespread protests and clashes, with reports of more than 180 deaths. The other options are unrelated to the 2019 unrest.
If ( x101 + 101) is divided by (x + 1), the remainder is:
A)
101
B)
100
C)
99
D)
0
Let f(x) = x^101 + 101. By the Remainder Theorem, when f(x) is divided by (x + 1), the remainder is f(-1). So, f(-1) = (-1)^101 + 101 = -1 + 101 = 100. However, the expression in the question is commonly intended as x^101 + 101 being divided by (x + 1), which gives remainder 100. Since 100 is option (b), that is the correct choice.
The ratio between two numbers is 5 : 6. If 5 is subtracted from each number, the ratio becomes 4 : 5. The numbers are:
A)
9, 10
B)
50, 60
C)
25, 30
D)
30, 36
Let the two numbers be 5x and 6x, since their ratio is 5:6. After subtracting 5 from each, the ratio becomes 4:5:
(5x - 5) / (6x - 5) = 4/5
Cross-multiplying:
5(5x - 5) = 4(6x - 5)
25x - 25 = 24x - 20
x = 5
So the numbers are 5x = 25 and 6x = 30.
Check: (25 - 5) : (30 - 5) = 20 : 25 = 4 : 5.
Hence, the correct answer is 25, 30.
Which is called the flower garden of Europe?
A)
Switzerland
B)
The Netherlands
C)
USA
D)

The Netherlands is popularly called the "flower garden of Europe" because of its world-famous flower cultivation, especially tulips, and its large flower export industry. Switzerland is known for mountains and scenic beauty, while USA and UK are not referred to by this title.
Zawma crosses a path 600 m long in 5 minutes. His speed in km/h is
A)
7.2
B)
12
C)
8.2
D)
10
Speed = distance/time. Here, distance = 600 m = 0.6 km and time = 5 minutes = 5/60 hour = 1/12 hour. So speed = 0.6 ÷ (1/12) = 0.6 × 12 = 7.2 km/h. Hence, the correct option is (a).
Firewall in computer is used for:
A)
Data transmission
B)
Authentication
C)
Monitoring
D)
Security
A firewall is a network security system used to protect a computer or network from unauthorized access and malicious traffic. It filters incoming and outgoing data based on security rules. Therefore, the correct use of a firewall is security. Data transmission, authentication, and monitoring are not its primary function.

The weight of 12 sheets of thick paper is 40g. How many sheets of the same paper would weigh 2.5 kg?
A)
100
B)
750
C)
830
D)
480
12 sheets weigh 40 g, so 1 sheet weighs 40/12 g = 10/3 g. 2.5 kg = 2500 g. Number of sheets = 2500 ÷ (10/3) = 2500 × 3/10 = 750. Therefore the correct answer should be 750, which corresponds to option (b).
In a group of 70 people, 50 people speak French, 20 speak Spanish and 10 speak both Spanish and French. How many speak at least one of these languages?
A)
10
B)
20
C)
50
D)
60
Use the formula for union of two sets:
Number speaking at least one language = French + Spanish - Both
= 50 + 20 - 10
= 60.
So, 60 people speak at least one of these languages. Option (d) is correct.
