The method of soil conservation in which bare ground between plants is covered with layer of organic matter like straw is called?

Accepted Answer

Mulching involves covering the bare soil between plants with organic matter like straw to retain soil moisture, regulate temperature, and prevent soil erosion.

Question 4

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 5

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 6

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 7

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 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 12

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 13

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 14

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 15

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 16

Question 18

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 19

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 20

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.
