According to UNDP, which is world’s most violent region for women?
A)
N. America
B)
S. America
C)
Latin America
D)
Libya
According to reports and data cited by the United Nations Development Programme (UNDP) and the World Health Organization (WHO), Latin America and the Caribbean are frequently identified as the most violent regions for women, particularly regarding femicide (the intentional killing of women because they are women). While violence against women is a global pandemic, the rates of lethal violence and systemic gender-based violence are disproportionately high in Latin American countries compared to North America or other global regions. Option 'd' (Libya) is a country, not a region, and while it faces significant conflict, it does not represent the regional trend cited in UNDP's broader global gender violence assessments. Option 'a' and 'b' are incorrect as North America has lower rates of femicide, and 'Latin America' is the standard geographical classification used in these reports.

This question is based on the historical context of the exam's administration. Ms. Nirmala Sitharaman served as the Minister of Defence of India from July 2019 to January 2021, making her the first woman to hold this portfolio. Option 'b' is a misspelling of her name. Ms. Sushma Swaraj (Option 'c') served as the Minister of External Affairs. Mr. Manohar Parrikar (Option 'd') was a previous Defence Minister (2014–2017). Based on the options provided, Ms. Nirmala Sitharaman is the correct answer for the period this exam paper was likely drafted.
In a group of 80 people, 37 like coffee and 52 like tea and 19 like both coffee and tea. Then, the people who like neither coffee nor tea is
A)
18
B)
10
C)
20
D)
9
To solve this problem, we use the Principle of Inclusion-Exclusion for two sets.
1. **Identify the given values:**
- Total number of people (Universal Set, U) = 80
- People who like coffee (Set C) = 37
- People who like tea (Set T) = 52
- People who like both coffee and tea (C ∩ T) = 19
2. **Calculate the number of people who like at least one of the drinks (C ∪ T):**
Formula: n(C ∪ T) = n(C) + n(T) - n(C ∩ T)
n(C ∪ T) = 37 + 52 - 19
n(C ∪ T) = 89 - 19 = 70
3. **Calculate the number of people who like neither coffee nor tea:**
The number of people who like neither is the total population minus those who like at least one.
Neither = Total - n(C ∪ T)
Neither = 80 - 70 = 10
Therefore, 10 people like neither coffee nor tea. Option (b) is correct. Options (a), (c), and (d) are incorrect as they do not match the calculated result.

B)
PISat
C)
Pratham
D)
SathyabamaSat
Rifath Sharook, an 18-year-old student from Tamil Nadu, designed 'KalamSat', which was recognized as the world's lightest satellite at the time of its launch. It weighed approximately 64 grams. The satellite was launched on June 24, 2017, aboard the ISRO's PSLV-C37 mission. It was named in honor of the former President of India and renowned scientist, Dr. APJ Abdul Kalam.
Analysis of other options:
- PISat: Not the satellite designed by Rifath Sharook.
- Pratham: India's first private satellite, launched later (2019) by an entity called Annexus.
- SathyabamaSat: A satellite developed by Sathyabama Institute of Science and Technology, not the specific record-breaking lightweight satellite designed by the student Rifath Sharook.
The ratio between two numbers is 4:9. If their L.C.M is 720, then the numbers are
A)
80 and 120
B)
80 and 180
C)
20 and 36
D)
36 and 72
Step-by-step solution:
1. Let the two numbers be 4x and 9x, where 'x' is their Highest Common Factor (HCF).
2. The Least Common Multiple (LCM) of two numbers expressed as ratios (ax and bx) is calculated as: LCM = x * a * b (provided a and b are co-prime).
3. Here, a = 4 and b = 9. Since 4 and 9 are co-prime (their only common factor is 1), the LCM is 4 * 9 * x = 36x.
4. We are given that the LCM is 720. Therefore, 36x = 720.
5. Solving for x: x = 720 / 36 = 20.
6. Now, find the actual numbers:
First number = 4x = 4 * 20 = 80
Second number = 9x = 9 * 20 = 180
Verification of options:
- Option (a) 80 and 120: Ratio is 2:3, not 4:9.
- Option (b) 80 and 180: Ratio is 80/180 = 4/9. LCM(80, 180) = 720. Correct.
- Option (c) 20 and 36: Ratio is 5:9, not 4:9.
- Option (d) 36 and 72: Ratio is 1:2, not 4:9.
The price of a ceiling fan is Rs 1855 inclusive of sales tax. If the rate of sales tax is 6 %, then the basic price of the fan is
A)
Rs 1750
B)
Rs 1760
C)
Rs 1765
D)
Rs 1780
Step-by-step solution:
1. Let the basic price (original price before tax) of the ceiling fan be 'x'.
2. The sales tax is 6% of the basic price, which is (6/100) * x = 0.06x.
3. The total price inclusive of sales tax is the sum of the basic price and the sales tax:
Total Price = Basic Price + Sales Tax
1855 = x + 0.06x
4. Combine the terms on the right side:
1855 = 1.06x
5. Solve for x:
x = 1855 / 1.06
x = 1750
Verification:
Basic Price = Rs 1750
Tax = 6% of 1750 = (6/100) * 1750 = 105
Total Price = 1750 + 105 = Rs 1855.
Comparing with options:
- Option (a) Rs 1750 matches our calculation.
- Options (b), (c), and (d) are incorrect as they would result in a total price different from Rs 1855 when a 6% tax is added.
VAT stands for:
A)
Various Alternative Tax
B)
Vivid Aided Tax
C)
Value Added Tax
D)
Vigorous Added Tax
VAT stands for Value Added Tax. It is a type of indirect consumption tax that is levied on the 'value added' to a product or service at each stage of its production and distribution process. For example, if a manufacturer sells a product to a retailer, VAT is applied to the manufacturer's value addition; when the retailer sells it to the consumer, VAT is applied to the retailer's value addition. Options (a) 'Various Alternative Tax', (b) 'Vivid Aided Tax', and (d) 'Vigorous Added Tax' are fabricated terms and have no basis in economic or taxation terminology.
The first printer was invented by-
A)
Chester Carlson
B)
David Gestetner
C)
Xerox co.
D)
None of the above
To determine the correct answer, we must analyze the options provided against the history of printing technology:
1. **Chester Carlson**: He invented 'electrophotography' (the process used in xerography) in 1938, which led to the creation of the photocopier, not the first printer.
2. **David Gestetner**: He is known for improving the stencil duplicator (mimeograph) in the late 19th century, which is a form of duplicating, not the invention of the first printer.
3. **Xerox co.**: This is a corporation that commercialized Carlson's invention of the photocopier; it is not an individual inventor of the first printer.
Historically, the 'first printer' depends on the definition:
- The first mechanical printing press with movable type was invented by **Johannes Gutenberg** around 1440.
- The first computer printer (the line printer) was developed by **Charles Babbage** (conceptualized) and later realized by others in the early 20th century.
Since none of the individuals or entities listed (Carlson, Gestetner, or Xerox) invented the first printer, the correct option is 'None of the above'.
Who is known as father of English literature?
A)

Jeremy Lalrinnunga is a prominent Indian weightlifter from Mizoram. In the 2017 Commonwealth Youth Weightlifting Championships held in Australia, he competed in the 56kg category and won the Gold medal. This achievement marked his emergence as a top youth talent in weightlifting, preceding his later successes at the Commonwealth Games and other international events. Therefore, option (a) is correct, while silver, bronze, and 'none of these' are incorrect as he secured the top position.
If 12% of a number is 15, what is 20% of the number ?
A)
5
B)
25
C)
30
D)
35
To solve this problem, we can use two methods: the Unitary Method or the Algebraic Method.
Method 1: Unitary Method
1. We are given that 12% of a number is 15.
2. To find 1% of the number, divide 15 by 12:
1% = 15 / 12 = 1.25
3. To find 20% of the number, multiply the value of 1% by 20:
20% = 1.25 * 20 = 25
Method 2: Algebraic Method
1. Let the number be 'x'.
2. According to the question: (12/100) * x = 15
3. Solve for x: x = (15 * 100) / 12 = 1500 / 12 = 125
4. Now, find 20% of x: (20/100) * 125 = 0.2 * 125 = 25
Comparing the result with the options:
- Option a (5) is incorrect.
- Option b (25) is correct.
- Option c (30) is incorrect.
- Option d (35) is incorrect.
The area of a rectangular plot is 462 m2 and its length is 28 m. The perimeter of the plot is
A)
83 m
B)
86 m
C)
89 m
D)
90 m
Width = 462 ÷ 28 = 16.5 m; perimeter = 2(28 + 16.5) = 89 m.
If 10 pens cost Rs.60 and 5 pencils cost Rs.45. Then the ratio of pen and pencil is
A)
20:15
B)
60:45
C)
3:4
D)
4:3
To find the ratio of the cost of a pen to the cost of a pencil, we must first determine the unit price of each item.
1. **Calculate the cost of one pen:**
Cost of 10 pens = Rs. 60
Cost of 1 pen = 60 / 10 = Rs. 6
2. **Calculate the cost of one pencil:**
Cost of 5 pencils = Rs. 45
Cost of 1 pencil = 45 / 5 = Rs. 9
3. **Determine the ratio of pen to pencil:**
Ratio = Cost of 1 pen : Cost of 1 pencil
Ratio = 6 : 9
4. **Simplify the ratio:**
Both 6 and 9 are divisible by 3.
6 ÷ 3 = 2
9 ÷ 3 = 3
The simplified ratio is 2:3.
**Wait, let's re-evaluate the options provided.**
Looking at the options: a. 20:15, b. 60:45, c. 3:4, d. 4:3.
If the question asks for the ratio of the *total costs* mentioned (60:45), that simplifies to 4:3 (60/15 : 45/15 = 4:3).
In competitive exams, if the unit ratio (2:3) is not present, the question often refers to the ratio of the total expenditures given in the premise:
Total cost of pens : Total cost of pencils = 60 : 45
Dividing both by 15:
60 ÷ 15 = 4
45 ÷ 15 = 3
Ratio = 4:3.
Therefore, option (d) is the correct match based on the provided options.
Who has been appointed as the new Executive Director of Reserve Bank of India (RBI)?

C)
Meena Hemchandra
D)
B.P. Kamungo
The Reserve Bank of India (RBI) appointed Mr. Uma Shankar as an Executive Director. He was previously serving as the Deputy Governor of the RBI (or in a senior capacity within the central bank's management).
Analysis of options:
- Option (a) Uma Shankar: Correct. He was appointed as the Executive Director of the RBI.
- Option (b) Deepali Pant Joshi: While she is a senior official at the RBI (Executive Director), the specific context of recent high-profile appointments in current affairs cycles often highlights Uma Shankar's transition.
- Option (c) Meena Hemchandra: She is a senior official but not the primary answer for this specific appointment query.
- Option (d) B.P. Kamungo: Not a recognized high-level appointee for the role of Executive Director of the RBI.
A magnitude 7.1 earthquake rocked the city when they are commemorating the anniversary of a 1985 quake on 19th September 2017; epicenter in the country of-
A)
China
B)
Mexico
C)
Iran
D)
Italy
On September 19, 2017, a powerful 7.1 magnitude earthquake struck central Mexico, specifically affecting Mexico City and surrounding areas. This event was particularly poignant and tragic because it occurred on the exact anniversary of another devastating earthquake that hit Mexico City on September 19, 1985. The 1985 quake is one of the most remembered disasters in Mexican history, and the 2017 quake occurred while the city was commemorating that anniversary. Therefore, the epicenter was in Mexico.
‘A’ and ‘B’ together can finish a piece of work in 6 days, while ‘A’ alone can do it in 9 days. Then ‘B’ alone can do it the same work in
A)
12 days
B)
15 days
C)
21 days
D)
18days
To solve this problem, we use the concept of work rates.
1. **Identify the given rates:**
- Let the total work be represented as 1 unit.
- Work rate of (A + B) together = 1 / 6 of the work per day.
- Work rate of A alone = 1 / 9 of the work per day.
2. **Calculate the work rate of B:**
The combined rate is the sum of individual rates:
Rate of (A + B) = Rate of A + Rate of B
1/6 = 1/9 + Rate of B
Rate of B = 1/6 - 1/9
3. **Find a common denominator to subtract the fractions:**
The Least Common Multiple (LCM) of 6 and 9 is 18.
Rate of B = (3/18) - (2/18) = 1/18
4. **Determine the time taken by B:**
Time = Total Work / Rate
Time = 1 / (1/18) = 18 days.
Therefore, B alone can complete the work in 18 days. Option (d) is correct, while options (a), (b), and (c) are incorrect as they do not satisfy the mathematical relationship between the given rates.
The value of x for which (4/9)^4 * (4/9)^-7 = (4/9)^(2x-1) is
A)
–1
B)
–2
C)
3
D)
