Given:

On a tree, there are some parrots and pigeons in the ratio of 7 ∶ 9.

After an hour 8 parrots fly and 6 pigeons and 10 sparrows come on the tree. The ratio of parrots and pigeons now is 1 ∶ 4.

Calculation:

Case 1:

Number of parrots = 7x

Number of pigeons = 9x

Case 2:

Number of parrots = 7x - 8

Number of pigeons = 9x + 6

Number of sparrows = 10

According to the question,

⇒ (7x - 8)/(9x + 6) = 1/4

⇒ 28x - 32 = 9x + 6

⇒ 19x = 38

⇒ x = 2

Number of parrots in new scenario = 7x - 8 = 6

The ratio of parrot and sparrow = 6 : 10 = 3 : 5

Therefore, "3 : 5" is the required answer.

Given:
The average age of Abhay, his wife, and their child 6 years ago = 42 years
The average age of Abhay's wife and their child 8 years ago = 30 years
Formulas Used:
Average Age = Total Age/Number of People
Average Age now = Age x years ago + Average age
Solution:
The average age of Abhay, his wife, and their child 6 years ago was 42 years.
So the average age of Abhay, his wife, and their child at present 42 + 6 = 48
Sum of the age of all three = 48 × 3 = 144\
Similarly
The average wife and their child 8 years ago was 30 years
The average wife and their child at present 30 + 8 = 38
Sum of the age of all wife and children = 38 × 2 = 76
Abhay age = 144 - 76 = 68.
Therefore, the present age of Abhay is 68 years

Given:
Simple interest rate = 8% and Time = 10 years
The interest amount was Rs. 560 less than the principal amount.
Formula used:
SI = PRT/100
Calculation:
According to the question,
The simple interest received is Rs. 560 less than the principal.
So, SI = P - 560.
P - 560= (P x 8 x 10)/100
⇒ 100P - 56000 = 80P
⇒ 20P = 56000
P = 56000/20 = 2800
∴ The amount lent is Rs. 2800.

Given:

Boat cover distance in upstream = 12 km

Boat Cover distance in downstream = 18 km

Total time = 3 hr

Boat cover distance in upstream = 36 km

Boat Cover distance in downstream = 24 km

Total time = 6 (1/2) hr

Formula Used:

(Distance)_upstream/(Speed of boat - speed of river) + (Distance)_downstream /(speed of boat + speed of river) = Total time

Calculation:

Let speed of boat be X and speed of river be Y

According to question,

⇒ 12/(X - Y) + 18/(X + Y) = 3 ----(1)

⇒ 36/(X - Y) + 24/(X + Y) = 13/2 ----(2)

By equation (1) × 3 - equation (2)

⇒ 54/(X + Y) - 24/(X + Y) = 9 - 13/2

⇒ 30/(X + Y) = 5/2

⇒ X + Y = 12 ----(3)

From equation (1)

⇒ 12/(X - Y) + 18/12 = 3

⇒ 12/(X - Y) = 3 - 3/2

⇒ X - Y = (12 × 2)/3

⇒ X - Y = 8 ----(4)

Solve equation (3) and (4)

⇒ 2y = 4

⇒ y =2

∴ Speed of current is 2 km/h.

Solution:

Let the number of red balls in the bag be x.

Probability of drawing a red ball from the bag initially = x/12
After 6 more red balls are added, the total number of red balls in the bag becomes x + 6.
New probability of drawing a red ball from the bag = (x + 6)/18

According to the problem, the new probability of drawing a red ball is twice the initial probability, i.e.,

2p = (x + 6)/18

⇒ 36p = x + 6

Also, we know that the initial probability of drawing a red ball is:

p = x/12

⇒ 12p = x

Substituting the value of x in terms of p in the equation 36p = x + 6, we get:

36p = 12p + 6

⇒ 24p = 6

⇒ p = 1/4

Substituting the value of p in the equation 12p = x, we get:

x = 3

Therefore, the bag initially had 3 red balls.

The correct answer is Dwarf.

• The high-yielding variety of seeds was popularly called dwarf variety.

Explanation

• With the help of repeated mutations, Mr. Bourlog had been able to develop a seed that was raised in its nature of nutrients supplied to the different parts of the wheat plants.
• These parts were against the leaves, stems and in favor of the grain.
• This made the plant dwarf and the grain heavier which resulted in a high yield.
• These seeds were non-photosynthetic, hence non-dependent on sun rays for higher yields.

The Correct Answer is Barley.

Plant nutrients:

• Plant nutrients can be classified according to their function or importance in plant life development and production.
• The three essential nutrients for plants are potassium, phosphorus, and nitrogen.

Explanation:

Manure:

• Manures are decomposed organic matter derived from plants and animals.
• Besides providing supplements of plant nutrients, manures are beneficial in many ways.
• They enhance biological activities in the soil, and also improve the structure, colour, aeration and water-holding capacity of the soil.
• After plastering, the manure takes around four to five months to be ready for usage.
• Manures are slow in decomposing, hence, they release plant nutrients gradually, which can be used as organic fertilisers in agriculture.

Thus, the manure takes 4-5 months to be ready to be used after plastering.

Other Related PointsCompost:

• The mass developed after the rotting of organic matter is called ‘compost’.
• Nowadays, super compost is also in vogue.
• It is developed using superphosphate @ 10–15 kg/t of raw material used.
• Farm waste, like sugarcane trash, paddy straw, plant debris, weeds or other waste materials are, generally, used by farmers to get compost.​

Vermicompost:

• Vermicompost is developed using earthworms.
• Earthworms consume organic matter and excrete it as cast.
• This cast is used as a vermicompost.
• It is rich in plant nutrients and beneficial bacteria and vascular arbuscular mycorrhiza (VAM) fungi.
• Depending upon the types of base material used, vermicompost, on average contains 3% nitrogen, 1% phosphorus and 1.5% potassium.

Fertilizer:

• They are plant nutrients manufactured commercially from inorganic chemicals.
• They are ready-to-use nutrients in concentrated forms and contain a much higher amount of nutrients than manure.

Concept:

• Every region follows different agricultural practice.
• Depending on the type of crop and scale of farming various agricultural practices are adopted.

Explanation:

About Shifting Cultivation:

• It is a type of subsistence farming in which the farmer cultivates on a plot of land temporarily, and when he finds the land infertile to grow due to soil exhaustion, they move on to another plot.
• It is largely practised in the north-eastern region of India, including Assam, Manipur, Mizoram, Nagaland, etc.
• This way of farming is also known as "Jhum Kheti".
• It is also called Slash and burn agriculture.
• It is a shifting cultivation practice.
• It is also known as fire-fallow cultivation.
• Forest land is cleaned and ashes are added to the soil.
• Cultivated spots/ areas are usually small.
• Short periods of crop occupation alternate with long fallow periods.
• Field rotation is practised instead of crop rotation.
• The farmer cultivates on a plot of land temporarily.
• When finding the land infertile to grow due to soil exhaustion, they move on to another plot.

Thus, the North-eastern region practice shifting cultivation in India.
