Given:

Airplane covers distance in 12 minutes = 300 km

Calculation:

Airplane covers distance in 12 minutes = 300 km

Airplane covers distance in 1 minute = 300/12 = 25 km

Airplane covers distance in 75 minutes = 25 × 75 = 1875 km 

∴ Option 2 is correct.

Given:

A is more efficient than B. B takes 6 days more than A to complete a work alone.

Calculation:

A is more efficient than B.

B takes 6 days more than A to complete a work alone.

Let time taken by A to complete the work = x days

Let time taken by B to complete the work = (x + 6) days

Efficiency of A = 140

Efficiency of B = 100

⇒ 140x = 100 (x + 6) = 100x + 600

⇒ 40x = 600

x = 15 days

∴ A alone can complete the same work in 15 days.

∴ Option 3 is correct.

Given:

The missing number in the series 8, 24, 12, 36, 18, 54, ______

Calculation:

The missing number in the series 8, 24, 12, 36, 18, 54, ______

Here, 

Second term = first term × 3 

Third term = second term /2

⇒ 24 = 8 × 3 

⇒ 12 = 24/2

⇒ 36 = 12 × 3

⇒ 18 = 36/2

⇒ 54 = 18 × 3 

⇒ 27 =54/2

∴ Option 2 is correct.

Given:

The average of five consecutive odd numbers is 21.

Concept used:

Average = Sum of all observations/ total number of observations

Calculation:

Let the  first five consecutive odd numbers :- (x), (x + 2), (x + 4), (x + 6) and (x + 8)

⇒ 21 = [(x) + (x + 2) + (x + 4) + (x + 6) + (x + 8)]/5

⇒ 5x + 20 = 105

⇒ 5x = 85

x = 17

∴ The least odd  number is 17.

∴ Option 3 is correct.

Given:

Side of cube = 7 cm

Height of cylinder = 196 cm

radius of cylinder = 14 cm

Formula used:

Volume of cylinder = πr²h

Volume of cube = a³; where a be the side of cube.

Calculation:

Side of cube = 7 cm

Height of cylinder = 196 cm

radius of cylinder = 14 cm

Let the Number of cubes formed by cylinder = n

n ×  a3 = πr2h

n × 7³ = 22/7 × 14 × 14 × 196

n =  (22 × 14 × 14 × 196)/ 7 × 7 × 7 × 7

n = 352

∴ Option 1 is correct.

Key Points

• A cryptocurrency is a data string that has been encrypted and represents a unit of currency.
• It is monitored and organized by a peer-to-peer network known as a blockchain, which also functions as a secure ledger of transactions such as buying, selling, and transferring.
• Cryptocurrencies, unlike physical money, are decentralized, which means they are not issued by governments or other financial institutions.
• Cryptocurrencies are created (and secured) through cryptographic algorithms that are maintained and confirmed in a process known as mining, in which transactions are processed and validated by a network of computers or specialized hardware such as application-specific integrated circuits (ASICs).
• The process rewards the miners who power the network with cryptocurrency.

Important Points FastCash is a convenient, paperless credit facility with no collateral required for your emergencies and urgent needs. It is not a cryptocurrency. 

Bitcoin, Ether, Litecoin, Z Cash, and Monero are popular cryptocurrencies. 

Therefore, the correct answer is Fastcash.

The United States rover which landed on Mars in February 2021 is Rover Perseverance under a mission Name Mars 2020.

Key PointsIndia's new National Education Policy (NEP) 2020 is set to replace the 10+2 schooling system in India with a new 5+3+3+4 system. 

As per the new school education system of 5+3+3+4 outlined in NEP 2020, children will spend 5 years in the Foundational stage, 3 years in the Preparatory stage, 3 years in the Middle stage, and 4 years in the Secondary stage. The division of stages has been made in line with the kind of cognitive development stages that a child goes through in early childhood, school years, and secondary stages.

Foundational years of 5 years

• This will consist of 3 years of pre-school/Anganwadi education and 2 years of primary education including classes 1 and 2. It will be for the age group from 3-8.
