Positive factors of 90 = 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

Total number of factors of 90 = 12

Positive even factors of 90 = 2, 6, 10, 18, 30, 90

Total number of even factors = 6

Therefore, probability = 6/12 = 1/2

Reason:
For 35 → 3² + 5² = 9 + 25 = 34.
So for 76 → 7² + 6² = 49 + 36 = 85.

The numbers at odd position increase by 4 while the numbers at even position increase by 2.

7+4=11

16+2=18

Carl David Anderson discovered the positron on August 2, 1932, for which he won the Nobel Prize for Physics in 1936

The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1 e, a spin of 1/2 (same as electron), and has the same mass as an electron.

Here, p = -2, q = -3

And, (pq + qr)p + p²q²r - pqr + pq² = 6

Then, ((-2)(-3) + (-3)r)(-2) + (-2)²(-3)²r - (-2)(-3)r + (-2)(-3)² = 6

(6r - 12) + 36r - 6r - 18 = 6

r = 1

The correct order is:- Speed- Accident- Injury- Hospital- Recovery

Suppose pipe B is closed after n minutes.

12/20 + n/15 = 1

=> n/15 = 2/5

=> n = 6

Hence option a is correct.

Dustin Johnson is an international golfer.

Sydney Barnes-English Cricketer.

Graham Gooch- English Cricketer.

Hansie Cronje- South African Cricketer.

Conclusion I follow because he got promoted as he performed well. Conclusion II does not follow because if he was transferred to the branch city Z it does not necessarily means that it was not performing well. It might be performing well while he was transferred to that branch.

The logic in the series is the difference and is shown below:

18 + 19 = 37

37 + 19 = 56

56 + 19 = 75

75 + 19 = 94

94 + 19 = 113

113 + 19 = 132

The correct order is:

B) Price at which shopkeeper sold the item to A = 125% of 600 = Rs.750

C) Marked price of the item by A = 750 + 300 = Rs.1050

A) Selling price of the item for A when sold at D% discount = (100 - D)% of 1050

D) Price at which A sold that item back to shopkeeper = (100 - D)% of 1050 = 840

100 - D = 80

D = 20

36th Constitutional Amendment Act:

Constitution has been amended every-time a new state or union territory is added. In this act Sikkim was made a full fledged state of Union of India.

Madabhushi Ananthasayanam Ayyangar was the first Deputy Speaker and then Speaker of Lok Sabha in the Indian Parliament. He was also the Governor of Bihar. In 1948 he was elected as Deputy Speaker of Lok Sabha with Ganesh Vasudev Mavlankar as the Speaker. After the death of Mavlankar in 1956, he was elected as Speaker of Lok Sabha.

• G.V. Mavlankar- First Speaker of Lok Sabha
• M. Thambidurai- Present Deputy Speaker of Lok Sabha.

The earth's axis makes an angle of 66 ½ degree with the plane of its orbit around the sun, influences the amount of insolation received at different latitudes.

• Higher the latitude the less is the angle they make with the surface of the earth resulting slant sun rays.
• The slant rays are also required to pass through greater depth of atmosphere resulting in more absorption, scattering, and diffusion.

We tabulate the given data as follows:

Percentage = (21 + 15 + 55)/(45 + 25 + 10) * 100% = 113.75%

Number of students in school B = number of students in school A - P

Also, number of students in school B = R - number of students in school A

Then, number of students in school A - P = R - number of students in school A

Number of students in school A = (R + P)/2

R S Saria Committee recommended on constitution of agricultural finance and cooperative societies.

Group 2: The lines intersecting are in increasing order.

Group 3: the intersecting triangles are added in each step.

Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (email) transmission. First defined by RFC 821 in 1982, it was last updated in 2008 with Extended SMTP additions by RFC 5321, which is the protocol in widespread use today.

George Yule became the first British president of Indian National Congress at Allahabad Session (1888).

Indian shuttler P V Sindhu won the bronze medal in the women's single match in Tokyo 2020 Olympics . PV Sindhu defeated He Bing Jiao of China by 21-13 and 21-15 in the bronze medal match and became the first Indian woman to win two Olympic medals. Sindhu won silver at Rio 2016. Wrestler Sushil Kumar is the first and only other Indian to win two Olympic medals. First Indian to win two olympic medal : Wrestler Sushil Kumar First Indian Woman to win Olympic medal : P V Sindhu

Efficiency ratio, A: B = (250/3)/100 = 5: 6

Time ratio, A: B = 6: 5

Again, efficiency ratio, B: C = 125/100 = 5: 4

Time ratio, B: C = 4: 5

Now, (1/A) + (1/B) + (1/C) = 1/30

(5/(6B)) + (1/B) + (4/(5B)) = 1/30

B = 79 days

Both conclusions I and II follow

Figure 1 will follow the series as the rectangle on the top is placed at the bottom-most left end in each step as a square.

Alexander Dalrymple Award is awarded in the recognition of outstanding contribution to Indian hydrography and across the wider Indian Ocean region.

• Frederick Sanger was a British biochemist who twice won the Nobel Prize in Chemistry, one of only two people to have done so in the same category (the other is John Bardeen in physics).
• In 1958, He was awarded a Nobel Prize in Chemistry "for his work on the structure of proteins, especially that of insulin".
• In 1980, Walter Gilbert and Sanger shared half of the chemistry prize "for their contributions concerning the determination of base sequences in nucleic acids". The other half was awarded to Paul Berg "for his fundamental studies of the biochemistry of nucleic acids, with particular regard to recombinant DNA".

• Bidesia is a form of dance drama which holds a unique place amongst folk dances from Bihar. It is believed to be created by Bhikari Thakur, a person who was barber by profession and left everything for his passion of drama. Bidesia deals with social issues & conflict between the traditional and modern, the rich and the poor and delicate matters like emotional battles.
• In old days, Bidesia was famous as it gave voice to many social concerned topics like the cause of poor laborers and tried to create awareness about the poor status of women in Bhojpuri society. Sometimes, the tone of Bidesia is sarcastic but it uses vibrant dance moves and music with emotional stories.
