Question 1

If a saree is sold for Rs 1900 the seller will face 5% loss, at what price (in Rs) should he sell the saree to gain 15% profit?

Accepted Answer

1900 represents 95% of the cost price. So, CP = 1900 / 0.95 = 2000. To gain 15% profit, the new selling price is 2000 * 1.15 = 2300.

Question 2

What is the value of Cot 45° + Cosec 60°?

Accepted Answer

We know that Cot 45° = 1 and Cosec 60° = 2/√3. Adding them together gives 1 + 2/√3 = (√3 + 2)/√3.

Question 3

What is the ratio of net exports in year 2016 to that in year 2012?

Accepted Answer

Identify the net exports for 2016 and 2012 from the data. Divide the value of 2016 by the value of 2012 and simplify the fraction to get the ratio 3:2.

Question 4

Xylem helps in transportation of which of the following?

Accepted Answer

Xylem is a vascular tissue in plants responsible for transporting water and dissolved minerals from the roots to the rest of the plant. Phloem transports food.

Question 5

What is the slope of the line 2x + 3y = 12?

Accepted Answer

Convert the equation to the slope-intercept form y = mx + c. 3y = -2x + 12, which gives y = (-2/3)x + 4. Thus, the slope m is -2/3.

Question 6

After a discount of 23% an article is sold for Rs 1848. What is the marked price (in Rs) of the article?

Accepted Answer

Let the Marked Price be x. After a 23% discount, the selling price is 77% of x. So, 0.77x = 1848. Solving this gives x = 1848 / 0.77 = 2400.

Question 7

In April 2017, diplomatic ties were re-established after 37 years between Cuba and _________.

Accepted Answer

In April 2017, Cuba and Morocco re-established diplomatic relations after a 37-year gap. Ties were originally severed in 1980 when Cuba recognized the Sahrawi Arab Democratic Republic.

Question 8

A marathon route starts and goes 21 km North, then there is a turn towards West where the route goes on for 7 km, then there is a turn towards North where the route goes on for 10 km, then there is a right turn from where the route goes on 7 km to reach the end. Where is it now with reference to its starting position?

Accepted Answer

The route goes 21 km North, 7 km West, 10 km North, and 7 km East (right turn). The East-West movements cancel out. Total North distance = 21 + 10 = 31 km.

Question 9

Accepted Answer

Vishwa Mohan Bhatt, a Grammy-winning Hindustani classical music instrumentalist known for the Mohan Veena, was awarded the Padma Bhushan in 2017 for his contribution to Art-Music.

Question 11

If (x2/yz) + (y2/zx) + (z2/xy) = 3, then what is the value of (x + y + z)3?

Accepted Answer

Multiply the given equation by xyz to get x³ + y³ + z³ = 3xyz. This algebraic identity holds true when x + y + z = 0. Thus, (x + y + z)³ = 0.

Question 12

The simple interest on a sum of money for 10 years is Rs 3130. If the principal becomes 5 times after 5 years, then what will be the total interest (in Rs) obtained after 10 years?

Accepted Answer

SI for 5 years is 3130/2 = 1565. Since principal becomes 5 times for the next 5 years, interest becomes 1565 × 5 = 7825. Total interest = 1565 + 7825 = 9390.

Question 13

Select the related word from the given alternatives. River : Stream :: Ocean : ?

Accepted Answer

Just as a stream represents the continuous flow of water associated with a river, a current represents the continuous, directed movement of water within an ocean.

Question 14

If after giving a discount of 18%, a book is sold for Rs 1599, then what will be the marked price (in Rs) of the book?

Accepted Answer

Let the Marked Price be MP. After an 18% discount, the Selling Price is 82% of MP. So, 0.82 × MP = 1599. MP = 1599 / 0.82 = 1950.

Question 15

Which among the following is not an account under Balance of Payment? ?

Accepted Answer

The Balance of Payments primarily consists of the Current Account, Capital Account, and Financial Account. Official Reserves are typically a sub-component of the Financial Account, not a standalone primary account.

Question 16

What is the simple annual growth rate (in %) of the number of students of Business from 2012 to 2016?

Accepted Answer

Calculate the total percentage growth from 2012 to 2016 using ((Final - Initial) / Initial) × 100. Then divide by 4 (number of years) to find the simple annual growth rate of 12.5%.

Question 17

For an object, the state of rest is considered to be the state of ______ speed.

Accepted Answer

When an object is at rest, it does not change its position with respect to time. Therefore, its speed is exactly zero.

Question 18

In the following question, select the missing number from the given series. 2, 5, 12, 27, ?

Accepted Answer

The pattern is multiply by 2 and add consecutive integers: 2×2+1=5, 5×2+2=12, 12×2+3=27. So, the next number is 27×2+4 = 58.

Question 19

A and B together do a job in 12 days and A could do the job in 20 days if he worked alone. How many days would B take to do the job if he worked alone?

Accepted Answer

Total work = LCM(12, 20) = 60 units. Efficiency of A+B = 60/12 = 5. Efficiency of A = 60/20 = 3. B's efficiency = 5 - 3 = 2. Time for B = 60/2 = 30 days.

Question 20
