Which among the following city in India has the highest availability of 4G according to a survey by ‘Open Signal’?
A)
Bangalore
B)
Hyderabad
C)
Dhanbad
D)

OpenSignal’s city-level 4G availability survey in India identified Hyderabad as the city with the highest 4G availability. Therefore, among the given options, Hyderabad is correct. The other cities listed were not reported as the top city in that survey.
Strait of Hormuz is located between:
A)
Morocco and Spain
B)
Russia and Alaska
C)
Malaysia and Indonesia
D)
Iran and Oman
The Strait of Hormuz lies between Iran to the north and Oman (Musandam Peninsula) to the south. It is a strategically important waterway connecting the Persian Gulf with the Gulf of Oman and the Arabian Sea. The other options are incorrect because Morocco-Spain is the Strait of Gibraltar, Russia-Alaska is the Bering Strait, and Malaysia-Indonesia is a different Southeast Asian strait region, not Hormuz.
At what rate per cent per annum simple interest will a sum of 25000 amount to 29000 in 2 years?
A)
4 %
B)
6 %
C)
5 %
D)
8 %
Using simple interest, Amount = Principal + Interest. Here, P = 25000 and A = 29000, so SI = 29000 - 25000 = 4000. For 2 years, SI = (P × R × T) / 100. Thus, 4000 = (25000 × R × 2) / 100 = 500R. So R = 4000 / 500 = 8%. Therefore, the correct answer is 8%.
A tank which has a leak in its bottom is filled in 20 hours. Had there been no leak in the bottom, it would have been filled in 15 hours. The leak can empty the tank in
A)
15 hours
B)
5 hours
C)
75 hours
D)
60 hours
Let the filling rate of the pipe be 1/15 tank per hour and the effective rate with leak be 1/20 tank per hour. So, the leak alone reduces the rate by 1/15 - 1/20 = (4 - 3)/60 = 1/60 tank per hour. Hence, the leak can empty the full tank in 60 hours. Therefore, the correct option is (d).
The additive inverse of (x-5)/(x+7) is
A)
-(x-5)/(x+7)
B)
-(x+5)/(x+7)
C)
(x-7)/(x+5)
D)
(x+5)/(x=7)
The additive inverse of any expression is the number/expression that adds to it to give 0. So, for \((x-5)/(x+7)\), the additive inverse is simply its negative: \(- (x-5)/(x+7)\). Adding them gives 0. The other options change the numerator or denominator and are not the exact negative of the given expression.
Which international financial institution is involved with the Indian metro projects?
A)
Asian Development Bank
B)
World Bank
C)
International Monetary Fund
D)
BRICS
The Asian Development Bank (ADB) has been involved in financing and supporting several metro rail projects in India. Among the given options, ADB is the international financial institution commonly associated with Indian metro projects. The IMF does not fund such infrastructure projects, and BRICS is not a financial institution in this context. While the World Bank has also supported some urban transport projects, the standard exam answer for Indian metro projects is Asian Development Bank.
A submarine known as INS Vela belongs to:
A)
Type 212 Submarine
B)
Soryu Class Submarine
C)
Agosta Class Submarine
D)
Scorpene Class Submarine
INS Vela (S21), the Indian Navy submarine commissioned in 2021, is one of the Kalvari-class submarines built under Project-75. The Kalvari class is based on the French Scorpene design, so INS Vela belongs to the Scorpene Class. The other options are different submarine classes used by other navies or older Indian acquisitions.
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. Zawma covers 600 m in 5 minutes. Converting to km/h: 600 m = 0.6 km and 5 minutes = 5/60 hour = 1/12 hour. So speed = 0.6 ÷ (1/12) = 0.6 × 12 = 7.2 km/h. Therefore, the correct option is (a).
The first country in Asia to legalise same sex marriage is:
A)
Japan
B)
Taiwan
C)
Hongkong
D)
Macau
Taiwan became the first country in Asia to legalise same-sex marriage. Its legislature passed the law in 2019, making it the first in Asia to do so. Japan has not legalised same-sex marriage nationwide, and Hong Kong and Macau have not done so either.
The sum of the first 100 natural numbers is
A)
10100
B)
5500
C)
5050
D)
5000
The sum of the first n natural numbers is n(n+1)/2. For n = 100, the sum is 100 × 101 / 2 = 5050. So the correct option is (c). The other options are incorrect because 10100 is double the actual sum, 5500 and 5000 do not match the formula.
How many women Member of Parliament are there in the 17th Lok Sabha?
A)

B)
79
C)
80
D)
81
The 17th Lok Sabha (elected in 2019) had 79 women Members of Parliament. This is the commonly cited official count for the House. Therefore, option (b) is correct. The other options 78, 80, and 81 do not match the published number.

D)
Cattle breeds
Sahiwal, Gir, Red Sindhi, Tharparkar, and Rathi are all well-known indigenous Indian breeds of cattle. They are bred mainly for milk production and are recognized as bovine breeds, not lamb, pig, or goat breeds. Therefore, the correct option is cattle breeds.

A)
Damodar River
B)

The Damodar River is known as the 'Sorrow of Bengal' because it caused frequent devastating floods in the Bengal region before flood-control measures were undertaken. The Kosi is called the 'Sorrow of Bihar,' while the Hooghly and Teesta are not known by this title.
Match the following: Name of Books: A. Runlum Nuthai B. Ka Lungkham C. Sihlipui D. Savun Kawrfual Author: 1. L.Z. Sailo 2. B.Lalthangliana 3. Romuanpuii Zadeng 4. Lalhmingchhuanga Zongte
A)
3 4 1 2
B)
3 1 4 2
C)
2 4 1 3
D)
1 2 3 4
The correct matching is:
A. Runlum Nuthai — 3. Romuanpuii Zadeng
B. Ka Lungkham — 4. Lalhmingchhuanga Zongte
C. Sihlipui — 1. L.Z. Sailo
D. Savun Kawrfual — 2. B. Lalthangliana
So the sequence is 3 4 1 2, which corresponds to option (a). The other options have the authors paired in incorrect order.
Indian Air Force (IAF) and Indian Space Research Organization (ISRO) have signed a Memorandum of Understanding (MoU) for astronaut selection and training which is known as:
A)
Aakash Programme
B)
Vayumandal Programme
C)
Gaganyaan Programme
D)
Baadal Programme
The MoU between the Indian Air Force (IAF) and ISRO for astronaut selection and training refers to the Gaganyaan human spaceflight programme. This programme involves selecting and training astronauts for India’s first crewed space mission. The other options are not official ISRO-IAF programme names.
A machinery worth 7500 is depreciated by 4%. Its value after one year will be:
A)
7450
B)
7300
C)
7100
D)
7200
Depreciation by 4% means the value becomes 96% of the original after one year.
New value = 7500 × 96/100 = 7500 × 0.96 = 7200.
So, the correct option is (d) 7200. The other options do not match a 4% reduction from 7500.
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 3.6. So, 15 × 3.6 = 54 km/h. Hence the correct answer is 54 km/h. The other options are not equal to 15 m/s.
The expression (x^2 + x - 6) / (x^2 - 4x + 4) in its lowest term is
A)
(x+3)/(x-2)
B)
(x-2)/(x+3)
C)
(x-3)/(x-1)
D)
(x+2)/(x-3)
Factor both numerator and denominator:
- x^2 + x - 6 = (x + 3)(x - 2)
- x^2 - 4x + 4 = (x - 2)^2
Now cancel the common factor (x - 2):
((x + 3)(x - 2)) / (x - 2)^2 = (x + 3) / (x - 2)
So the expression in lowest terms is (x + 3)/(x - 2).
Kima covers a distance of 43.2 km on his bicycle in 3 hours. In 5 hours, he will cover a distance of
A)
72 km
B)
75 km
C)
216 km
D)
129.6 km
Speed = distance ÷ time = 43.2 ÷ 3 = 14.4 km/h. In 5 hours, distance = speed × time = 14.4 × 5 = 72 km. However, 72 km is option (a), so that is the correct answer.
A set of instructions also called a procedure or function that is used to perform a certain task is called:
A)
Analog
B)
Algorithm
C)
Autoresponder
D)
API
A set of instructions or a procedure used to perform a specific task is called an algorithm. An algorithm is a step-by-step method for solving a problem or completing a task.
Why others are incorrect:
- Analog: refers to a type of signal or system, not a set of instructions.
- Autoresponder: an email/message system that sends automatic replies.
- API: Application Programming Interface, a way for software programs to communicate, not the procedure itself.
