Cache

Why this answer is correct

Cache memory, also called CPU memory, is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. This memory is typically integrated directly with the CPU chip or placed on a separate chip that has a separate bus interconnect with the CPU. The basic purpose of cache memory is to store program instructions that are frequently re-referenced by software during operation. Fast access to these instructions increases the overall speed of the software program.

View answer & explanation

Correct answer

Answer: (b)B.

C

Why this answer is correct

Given:

A shopkeeper cheats to the extent of 11% while buying and selling fruits

Formula used:

Profit% = (Profit/CP)× 100

Where, CP = Cost Price, SP = Selling Price

Profit = SP - CP 

Calculation:

Let's assume the CP is Rs. 100

The shopkeeper cheats 11% at the time of buying 

Purchasing price = 100 × (100 - 11)/100

⇒ New CP = Rs. 89

New selling price, Shopkeeper sells an article cheats at 11%

⇒ 100 × (100 + 11)/100

⇒ Rs. 111

Profit% = ((111 - 89)/89)× 100

⇒ 24.71%

∴ His total gain in percentage is 24.71%

View answer & explanation

Correct answer

Answer: (d)D.

D

Why this answer is correct

Given:

Time taken by the first hole alone to empty the flask = 9 minutes

Time taken by the second hole alone to empty the flask = 16 minutes

Concept Used:

If the hole takes "a" minutes to empty a completely filled flask, then the part of the flask emptied by the hole in one minute = 1/a

Calculation:

Part of the flask emptied in one minute by first hole alone = 1/9

Part of the flask emptied in one minute by second hole alone = 1/16

Part of the flask they both empty in one minute, when working together is obtained as:

(1/9) + (1/16) = 25/144

∴ The time taken by both the holes to empty the flask working together = 144/25 = 519255\frac{{19}}{{25}} minutes

 

Total work = 144

Both pipe empty the tank in = 144/25 = 519255\frac{{19}}{{25}} minutes

    Hailstorm

  3. COption (c)

    Water falling back quickly from the beach.

  4. DOption (d)

    Pets acting strangely

View answer & explanation

Correct answer

Answer: (c)C.

Water falling back quickly from the beach.

Why this answer is correct

As the coastal ocean waters recede from the shore, it often leaves large portions of the sea floor exposed. Individuals who do not recognize this as a common precursor to tsunami waves often find themselves gravitating toward the exposed shore. Unfortunately, they often perished as they rush to gather fish left high and dry on the exposed beach or to view never before seen rock and reef formations —  only to be hit moments later by the incoming wall of water. Experts believe that a receding ocean may give individuals more familiar with “nature’s tsunami warning signal” as much as a five minute warning to evacuate the area. This cycle may be repeated several times as successive wave crests arrive five minutes to an hour apart.

Answer: (c)C.

C

Why this answer is correct

Concept

If each data is multiplied by a, then the variance is multiplied by a2.

Calculation

The variance of data 2, 4, 5, 6, 8, 17 is 23.33.

The variance of 4, 8, 10, 12, 16, 34 = 2 × (2, 4, 5, 6, 8, 17)w will be :

The variance of 4, 8, 10, 12, 16, 34 = 22 × 23.33 = 93.33

We must multiply the variance with 22 when we are multiplying the numbers with 2.  

Many a time the variance is multiplied by 2 instead of 22 which is wrong as the concept is - variance is multiplied by a2 when each data is multiplied by a.

View answer & explanation

Correct answer

Answer: (d)D.

D

Why this answer is correct

Given:

Selling price of the a bus = Rs. 22100

Loss = 15%

Formulae Used:

For an item sold at some profit on the CP, the selling price becomes:

SP = [(100 + %Profit)/100] × CP      ----(i)

For an item sold at some loss on the CP, the selling price becomes:

SP = [(100 – %Loss)/100] × CP      ----(ii)

Calculation:

Using the equation (ii), we get the CP of the bus as:

CP of the bus = 22100 × (100/85)      ----(iii)

Using the value of CP from equation (iii), and equation (i), we get:

New selling price of the bus = 22100 × 100/85 × 115/100 = 29900

∴ The new selling price of the bus will be Rs.29,900

Correct answer

Answer: (a)A.

A

Why this answer is correct

Shortcut Trick

Using standard Pythagorean triplets: (8, 15, 17) for angle A and (7, 24, 25) for angle B.

From tan A = 15/8, we directly get sin A = 15/17 and cos A = 8/17.

From tan B = 7/24, we directly get sin B = 7/25 and cos B = 24/25.

Applying the identity: cos(A + B) = cos A × cos B − sin A × sin B

cos(A + B) = (8/17 × 24/25) − (15/17 × 7/25) = 192/425 − 105/425 = 87/425.

∴ The correct answer is 87/425.

Alternate Method

Given:

tan A = 15/8 (Opposite / Adjacent)

tan B = 7/24 (Opposite / Adjacent)

Formula Used:

Hypotenuse2 = Opposite2 + Adjacent2

cos(A + B) = cos A × cos B − sin A × sin B

Calculations:

⇒ For Triangle A: Hypotenuse = √(152 + 82) = √(225 + 64) = √289 = 17

⇒ sin A = Opposite / Hypotenuse = 15/17

⇒ cos A = Adjacent / Hypotenuse = 8/17

⇒ For Triangle B: Hypotenuse = √(72 + 242) = √(49 + 576) = √625 = 25

⇒ sin B = Opposite / Hypotenuse = 7/25

⇒ cos B = Adjacent / Hypotenuse = 24/25

⇒ cos(A + B) = (8/17 × 24/25) − (15/17 × 7/25)

⇒ cos(A + B) = 192/425 − 105/425

⇒ cos(A + B) = 87/425

∴ The correct answer is 87/425.

Britain

Why this answer is correct

An independent panel of British scientists and experts has formally given nod to introduce so-called three-parent baby fertility treatments or mitochondrial gene therapy (MGT) procedures. The panel tasked with reviewing the safety of MGT held that this practice should be cautiously adopted to prevent certain genetic diseases from being passed on to future generations. Thus, it paves the way for the country to officially introduce the procedures. Earlier in February 2016, British Parliament voted to legalise three-parent baby fertility treatments or MGT procedures. It was first country in the world to legalise creation of In-Vitro Fertilisation babies with DNA from three people. The world’s first three-parent baby boy was born in Mexico in April 2016 to a Jordanian couple with help of this new fertility technique which incorporates DNA from three people in embryo.

View answer & explanation

Correct answer

Answer: (d)D.

People act both through the electoral system and the group process

Why this answer is correct

In Western European political science, the term polyarchy was used by Robert Dahl to describe a form of government in which power is invested in multiple people. It takes the form of neither a dictatorship nor a democracy. This form of government was first implemented in the United States and France and was gradually adopted by many other countries (Dahl, p. 234, 1989) Including Canada after the signing of the NAFTA agreement by Canadian Prime Minister Brian Mulroney in 1994. According to Dahl, the fundamental democratic principle is “the continuing responsiveness of the government to the preferences of its citizens, considered as political equals” with unimpaired opportunities (Dahl, 1971). A polyarchy is a state that has certain procedures that are necessary conditions for following the democratic principle. In semblance, the word polycracy describes the same form of government, although from a slightly different premise: a polycracy is a state ruled by more than one person, as opposed to a monocracy. The word is derived from Greek poly which means "many" and kratos which means "rule" or "strength."

View answer & explanation

Correct answer

Answer: (a)A.

The refractive index of the different layers of earth’s atmosphere changes continuously; consequently the position of the star’s image changes with time.

Why this answer is correct

The theory behind stars twinkling the refractive index of the different layers of earth’s atmosphere changes continuously; consequently the position of the star’s image changes with time.

CONCEPT:

  • Refractive Index: The Refractive index measures the bending of a ray of light when passing from one medium into another medium.
  • Every medium has a different refractive index value.
  • The refractive index of a medium is given by n = c / v

where c is the speed of light and v is the speed of light in the medium.

  • Our earth consists of mainly 6 layers.​​
  1. ​Troposphere 2. Stratosphere 3. Mesosphere 4. Thermosphere 5. Ionosphere 6. Exosphere

EXPLANATION:

  • A star appears to twinkle due to the atmospheric refraction of starlight.
  • Our earth consists of many layers.​​
  • The starlight when enters the earth’s atmosphere, undergoes refraction through different layers of atmosphere before it reaches the earth.

 

  • The atmospheric refraction occurs in a medium due to gradually changing the refractive index of the different mediums.
  • This makes a star to twinkle for our eyes.
  • So the correct answer will be option 1.
