• Since both the premises are universal and one premise is negative, the conclusion must be universal negative.
• (2) is the converse of the second premise and thus it  holds.

Being a responsible citizen and a regular visitor to the library, you may not stop from taking some proper action to help improve the condition of the library. Informing newspaper reporter to make a report is the best way to tackle the problem besides this it is necessary to write to the concerned authority to take action. Thus, option (d) is the best answer.

The Square Kilometre Array (SKA) is a radio telescope developed in Australia and South Africa which will have a total collecting area of one square kilometre. Atleast 13 countries and close to 100 organisations are involved radio telescopes collect radio wave from objects million or billions light years away from earth.

At present, multiple government agencies, like the Food Corporation of India (FCI), Central Warehouse Corporation, Warehouse Development Regulatory Authority, Railways, and the civil supply departments of states are involved in grain management.

Distance he could travelled/speed diff.
= 20/(14-10)
= 20/4
= 5 hrs
Now his actual speed was 10 km/h
Total distance travelled by him = speed × time
= 10 × 5
= 50 km.
 

To solve this problem, let's first find out the total time Anoop takes to read all four passages and answer all the questions.

Let the time he takes to read one passage be T. Since there are four passages, he takes 4T time to read all the passages. It is given that he can answer 12 questions in the time he takes to read one passage. So, the time he takes to answer one question is T/12.

There are a total of 5+8+8+6 = 27 questions. The time he takes to answer all the questions is 27 * (T/12) = 27T/12 = 9T/4.

Now, the total time spent on the section is the sum of the time spent on reading all the passages and answering all the questions: 4T + 9T/4 = 25T/4.

To cut down on his total time spent on the section by 20%, the new total time should be 80% of the original time, which is 0.8 * (25T/4) = 5T.

Since the time spent on answering the questions remains constant, the time spent on reading should reduce to 5T - 9T/4 = 11T/4. The new time he takes to read one passage is (11T/4) / 4 = 11T/16.

Now, let's find out the percentage increase in reading speed. The original time to read one passage is T, and the new time is 11T/16. Since speed is inversely proportional to time, the new speed will be 16/11 times the original speed.

The percentage increase in speed is [(16/11 - 1) * 100] = [(5/11) * 100] = 45.45%.

So, Anoop should increase his reading speed by 45.45% to cut down on his total time spent on the section by 20%.

Given, SI = Rs 929.20
P = ?
T = 5 years
R = 8%
P = (100 x SI) / RT
⇒ (100 x 929.20) / (8 x 5)
⇒ Rs. 2323

DRAMs are less expensive and slower than SRAMs. DRAM requires to be refreshed periodically as opposed to the SRAM. DRAM has higher bit density and lower power consumption.

India has 40 World heritage sites—seven natural world heritage sites, 32 cultural world heritage sites, and one mixed world heritage site. The Ancient Monuments and Archaeological Sites and Remains Act, 1958, and the Antiquities and Art Treasures Act, 1972, provide for the protection of the country’s heritage.

In cold countries, when the temperature of fresh water reaches 4°C, the layers of water near the top in contact with cold air continue to lose heat energy and their temperature falls below 4°C. On cooling below 4°C, these layers do not sink but may rise up as fresh water has a maximum density at 4°C. Due to this, the layer of water at 4°C remains at the bottom and above this layers of water 3°C, 2°C, 1°C and 0°C are formed. Because ice is a poor conductor of heat, it does not absorb heat energy from the water beneath the layer of ice which prevents the water freezing. Thus, aquatic creatures survive in such places.

5^th term of GP = ar^5-1 
⇒ 16*r⁴ = 81
⇒ r = (81/16)^1/4 = 3/2
4^th term of GP = ar^4-1 
⇒ 16*(3/2)³ = 54.

Insects and some other invertebrates exchange oxygen and carbon dioxide between their tissues and the air by a system of air-filled tubes called tracheae. Tracheae open to the outside through small holes called spiracles. Spiracles open into large tracheal tubes. These, in turn, lead to ever-finer branches. The branches penetrate to every part of the body. At their extreme ends, called tracheoles, they may be less than 1 m in diameter and are probably filled with liquid. Every cell in the insect's body is adjacent to, or very close to, the end of a tracheole.

Silver is the best conductor of electricity

• Tornadoes are whirling, vertical air columns that form from thunderstorms and stretch to the ground. They travel with ferocious speed and lay waste to everything in their path.
• When winds vary in speed or direction at different altitudes–a condition known as wind shear–the updraft will start to spin.
• These changes in winds produce the spin necessary for a tornado. For especially strong tornadoes, changes are needed in both the wind’s speed and direction.

Volume is maximum when radius is equal to height.

According to the rule (2) when 'one' is at the top, then 5 will be at the bottom.

Basmati exports are mainly to the Persian Gulf countries and, to some extent, the US and UK. Non-basmati shipments are more diversified, with the destinations spread across Asia (Bangladesh, China, Sri Lanka, Malaysia, Vietnam, UAE and Iraq) and Africa (from Senegal, Ivory Coast and Benin to Somalia and Madagascar). It’s non-basmati that has made India the biggest rice exporter, ahead of Thailand.

Cultivation of genetically-modified Bt cotton and high global prices had enabled India to become the world’s top producer (ahead of China) and No. 2 exporter (after the US) of the natural fibre.

Out of these only Carbon (C) is a non-metal whereas the others are all metals.

The environment performs four vital functions (i) it supplies resources: resources here include both renewable and non-renewable resources. (ii) it assimilates waste (iii) it sustains life by providing genetic and bio diversity and (iv) it also provides aesthetic services like scenery etc. The environment is able to perform these functions without any interruption as long as the demand on these functions is within its carrying capacity. This implies that the resource extraction is not above the rate of regeneration of the resource and the wastes generated are within the assimilating capacity of the environment.

Absorptive capacity means the ability of the environment to absorb degradation.

Pectin present in cell wall of plant cell is responsible for hardness of fruit coat. Polygalacturonase is induced into the fruit that degrade the pectin and soften the fruit.
