Rewriting the directory structure or file system of a disk is called:
A)
Flash Memory
B)
File Format
C)
Formatting
D)

Therefore, the correct answer is Thumbnail.
If the interest is compounded half-yearly, then the time period becomes twice and rate is:
A)
one-fourth
B)
halved
C)
same
D)
doubled
For compound interest compounded half-yearly, the time period is counted in half-years, so the number of compounding periods becomes twice. Since interest is applied twice as often, the annual rate must also be divided by 2 for each half-year period. Hence, the rate becomes halved. Option (c) is wrong because the rate is not kept the same per compounding period, and (a) and (d) are also incorrect.

The question refers to Forbes Magazine’s customer satisfaction/ranking survey associated with World Bank data, where HDFC Bank was ranked top among banks in India by customers. Hence, option (c) is correct. State Bank of India, Yes Bank, and ICICI Bank are not the top-ranked bank in that survey.
The sum of two numbers is 27 and their product is 182. Then the numbers are
A)
12 and 15
B)
13 and 14
C)
11 and 16
D)
8 and 19
Let the numbers be x and y. Then x + y = 27 and xy = 182. We check the options: 13 + 14 = 27 and 13 × 14 = 182, so they satisfy both conditions. The other options do not give both the required sum and product.
In a mixture of 120 litres, the ratio of milk and water is 2:1. What amount of water must be added to make the ratio of milk and water as 1:2?
A)
40 litres
B)
80 litres
C)
120 litres
D)
100 litres
Initial mixture = 120 L with milk:water = 2:1. So milk = 80 L and water = 40 L. Let x litres of water be added. Then milk remains 80 L, water becomes (40 + x) L. For the new ratio milk:water = 1:2, we need 80 : (40 + x) = 1 : 2. Cross-multiplying gives 160 = 40 + x, so x = 120. Hence, 120 litres of water must be added. Option (c) is correct.
The country which emit the largest quantity of Ozone depleting CFC-11 is:
A)
USA
B)
China

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. After subtracting 5 from each, the ratio becomes 4:5, so (5x - 5)/(6x - 5) = 4/5. Cross-multiplying gives 25x - 25 = 24x - 20, hence x = 5. Therefore, the numbers are 25 and 30. Option (c) is correct. The other options do not satisfy both ratios.
Who is the Minister in Charge of the Ministry of North Eastern Region in the Modi 2.0 government?
A)
Jitendra Singh
B)

D)
Bijoy Krishna Handique
In the Modi 2.0 government, the Ministry of Development of North Eastern Region (DoNER) was handled by Jitendra Singh. He was the Minister of State (Independent Charge) for the Ministry of Development of North Eastern Region. The other options are incorrect because Gen. V.K. Singh was associated with External Affairs/Road Transport, while Paban Singh Ghatowar and Bijoy Krishna Handique served in earlier governments, not Modi 2.0.
How many two digit natural numbers are divisible by 3?
A)
99
B)
33
C)
30
D)
25
Two-digit natural numbers run from 10 to 99. The multiples of 3 in this range are 12, 15, ..., 99. This is an arithmetic sequence with first term 12, last term 99, and common difference 3. Number of terms = ((99 - 12) / 3) + 1 = 30 + 1 = 30? Let's check carefully: the two-digit multiples of 3 are 12, 15, 18, ..., 99. The count is 30 terms? Using formula n = (99/3) - (9/3) = 33 - 3 = 30, but that counts 3, 6, 9 as well if not careful. Actually the number of multiples of 3 from 1 to 99 is 33, and from 1 to 9 is 3, so from 10 to 99 it is 33 - 3 = 30. Therefore the correct answer is 30, which corresponds to option (c).
Who has been appointed as India’s National Security Adviser?

A)
3 4 1 2
B)
3 1 4 2
C)
2 4 1 3
D)

Match each zoo with its location: Nandankanan Zoological Park is in Bhubaneswar (3), Nehru Zoological Park is in Hyderabad (4), Sakkarbaug Zoological Park is in Junagadh (1), and Jijamata Udyan is in Mumbai (2). Therefore the correct sequence is 3 4 1 2, which corresponds to option (a).
‘Even though Mercury is closer to the Sun than Venus, Mercury is colder.’ What is the reason?
A)
Lack of magnetic field
B)
It has more Carbon dioxide
C)
Greeenhouse effect
D)
It has fumes of Sulphuric Acid
Venus is much hotter than Mercury because its dense carbon dioxide atmosphere traps heat strongly, producing an intense greenhouse effect. Mercury has almost no atmosphere, so it cannot retain heat well and becomes colder overall despite being closer to the Sun. The other options are incorrect: magnetic field is not the main temperature reason, Mercury does not have more carbon dioxide, and sulfuric acid fumes are associated with Venus, not Mercury.
