The correct answer is Venus.

• Almost all celestial rotation in our solar system is from West to East, or counterclockwise when looking down from the North pole.
• The two exceptions are Venus and Uranus.
• Uranus' rotational axis is tilted by slightly more than 90 degrees with respect to its orbital plane.
• Venus is the only planet in the solar system that truly exhibits reverse rotation, spinning in the opposite direction to its orbital motion.

 

Key Points

• There is no force that causes the planets to rotate.
• Most of the rotation comes about from the conservation of angular momentum.
• Angular momentum is given by L=mwr² where m is the mass, w is the angular velocity in radians per second, and r is the radius of the circular motion.
• The bottom line is that stars like the Sun spin from the original angular momentum that was there in the solar nebula from which it formed.

The logic follows here is:

Code for weekdays:

 

 

October has 31 days, Gandhiji's birthday is on 2^nd October so the number of days remaining in October is 31 - 2 = 29 days.

November has 30 days.

Christmas is on 25^th December.

Total number of days is 29 + 30 + 25 = 84 days = 12 weeks and 0 odd days

So, Sunday + 0 = Sunday.

Hence, the correct answer is "Sunday".

According to the given information:

 

The given equation will be written as,

10 ÷ 5 + 3 × 2 - 3

Now by using the BODMAS rule:

10 ÷ 5 + 3 × 2 - 3

= 2 + 3 × 2 - 3

= 2 + 6 - 3

= 8 - 3

= 5

Hence, the correct answer is "5".

The correct answer is 21^st June.

• The International Day of Yoga has been celebrated annually on 21 June.
• It started in 2015.
• The International Yoga Day 2020 theme is "Yoga at Home and Yoga with Family".
• The International Yoga Day 2019 theme was "Climate Change" and it will be celebrated at United Nations on 20 June 2019 with "Yoga with Gurus" followed by a panel discussion on 21 June.

 

Important Points

• World No Tobacco Day is celebrated around the world every year on May 31.
• This year's theme is the protection of younger generations, focusing on “Protecting youth from industry manipulation and preventing them from tobacco and nicotine use”.
• In India, the National Doctors' Day is celebrated on July 1 to honor the legendary physician and the second Chief Minister of West Bengal, Dr. Bidhan Chandra Roy.
• The theme of this year's Doctors Day is "Lessen the mortality of COVID 19".
• World AIDS Day takes place on 1 December each year.
• The theme for the 2020 observance is “Ending the HIV/AIDS Epidemic: Resilience and Impact”.

Given: 

Sum of Money becomes 3 times

Rate of simple interest = 5% per annum

Formula Used;

Simple interest = (Principal × rate × time)/100

Amount =  Principal + Simple interest

Calculation:

Let the principal be Rs A

Then after tripling Amount will become 3A

Simple interest = 3A - A = 2A

2A = (A × 5 × time)/100

⇒ Time = (2A × 100)/(A × 5) = 40 years

∴ The Time period is 40 years.

Given: 

20% of boys and 30% of girls are scholarship holders

Concept:

Let number of students in the class be 5x

we know that ratio of number of boys and girls in the class: 3:2

let number of girls and boys students in the class be  2x and 3x respectively.

Calculation:

percentage of boys scholarship holder in the class :20%

number of boys scholarship holder in the class:

⇒20% of 3x = 0.6x

percentage of girls scholarship holder in the class: 30%

number of girls scholarship holder in the class:

⇒ 30% of 2x = 0.6x

Total students having scholarship = 0.6x + 0.6x = 1.2x

percentage of scholarship holder in the class:

⇒ (1.2x/5x)× 100 % = 24%

Conclusion:

percentage of students who are not scholarship holder:

⇒ 100 - 24 = 76%

The correct answer is Article - 368.

• The Constitution of India provides for its amendment to adjust itself to the changing conditions and needs.
• Article 368 in Part XX of the Constitution deals with the powers of Parliament to amend the Constitution and its procedure.

Additional Information 

• The Constitution of India talks about three types of emergencies:
• National Emergency in Article 352.
• President's Rule in State is mentioned under article 356.
• Financial Emergency in Article 360 of the Indian Constitution.
• Article 360 gives authority to the President of India to declare a financial emergency.
• Article 362 Constitution of India is Rights and privileges of Rulers of Indian States.
• Article 370 of the Indian constitution gave special status to Jammu and Kashmir, which was administered by India as a state from 1954 to 31 October 2019.

Important Points On the 5^th of August 2019, Prime Minister Shri Narendra Modi Ji took a visionary decision to abrogate Article 370.

Given:

The sum of two numbers = 25

The difference of two numbers = 13

Formula Used:

 If x and y are two numbers, then

xy = [(x + y)² - (x - y)²]/4

Calculation:

Let x and y be two numbers.

According to the question,

x + y = 25 and x - y = 13

Now, xy = [(x + y)2 - (x - y)2]/4 

⇒ [(25)2 - (13)2]/4

⇒ [625 - 169]/4

⇒ 456/4

⇒ 114

∴The product of two numbers is 114.

Here, x = [(x + y) + (x - y)]/2

⇒ [25 + 13]/2

⇒ 38/2

⇒ 19

Similarly, y = [(x + y) - (x - y)]/2

⇒ [25 - 13]/2

⇒ 12/2

⇒ 6

Now, xy = 19 × 6

⇒ 114

∴The product of two numbers is 114.

Given years are century years:

1600, 1700, 1800, 1900, 2000, 2100, 2200, 2300, and 2400

Checking for leap century years (Should be divisible by 400) :

1600 ÷  400 = 4 (Divisible by 400)

1700 ÷  400 = (Not Divisible by 400)

1800 ÷  400 = (Not Divisible by 400)

1900 ÷  400 = (Not Divisible by 400)

2000 ÷  400 = 5 (Divisible by 400)

2100 ÷  400 = (Not Divisible by 400)

2200 ÷  400 = (Not Divisible by 400)

2300 ÷  400 = (Not Divisible by 400)

2400 ÷  400 = 6 (Divisible by 400)

1600, 2000, and 2400 are leap century years.

Hence, the correct answer is "3".

Important Points

A leap year is divisible by 4.

But a century leap year should be divisible by 400. 

Every century year seems to be  a leap year because it is divisible by 4 and the year 4 years back is also a leap year.

But the length of the solar year, however, is slightly less than 365¼ days-by about 11 minutes.

To compensate for this discrepancy, the leap year is omitted three times every four hundred years.

Hence, a century year is not a leap year unless it is divisible by 400.
