Maharashtra Police Constable Mock Test - 10 - Maharashtra Police Constable MCQ

• ​Magadha was an ancient kingdom located on the Indo-Gangetic plains in eastern India and spread over what is today the modern state of Bihar. Hence, the correct option would be South of Ganga.
• At the height of its power, it claimed suzerainty over the entire eastern part of the country and ruled from its capital at Pataliputra (modern Patna, Bihar).
• In 326 BCE, when Alexander the Great was camped at the river Beas on the westernmost part on India, his army mutinied; they refused to march further east. They had heard about the great Magadha kingdom and were unnerved by stories of its might.
• Unwillingly, Alexander turned back. But this was not the first time that the might of Magadha had forced kings westwards.
• One of the earliest references to Magadha is in the epic Mahabharata, where we see the entire Yadava clan abandoning their homeland on the Gangetic plains to migrate south-westwards towards the desert-ocean land to avoid constant battles with their eastern neighbour, Magadha.

• MethaneSAT will track and measure methane emissions at a global scale. It is equipped with a high-resolution infrared sensor and a spectrometer. It can track differences in methane concentrations as small as three parts per billion in the atmosphere. It also has a wide-camera view — of about 200 km by 200 km — allowing it to identify larger emitters so-called “super emitters”.

Statement 2

• It will orbit the Earth 15 times a day, monitoring the oil and gas sector. It will create a large amount of data, which will tell “how much methane is coming from where, who’s responsible, and are those emissions going up or down over time”.

The MethaneSAT satellite was launched aboard a SpaceX Falcon9 rocket from California.

• Cycas circinalis is an evergreen palm-like tree that grows up to 25 ft. It typically occurs in fairly dense, seasonally dry scrubby woodlands in hilly areas. It is also facultative deciduous in extremely dry times. Eenthu Pana is like areca nut. It cannot be prepared unless it’s completely dry and this is difficult as it’s usually plucked in the rainy season.

Statement 2

• It is a nutraceutical plant for several indigenous communities in the Western Ghats

Statement 3

• It is known to be an Indian endemic, restricted to the Western Ghats, in the states of Kerala, Karnataka, Tamil Nadu, and the south of Maharashtra. Out of the nine species of cycads recognised within India, six are endemic.

Cycas circinalis is on the verge of extinction in the northern part of the Kerala after being hit by an unknown and fast spreading plant disease.

• Holistic Progress Card incorporates feedback from parents, classmates, and even self-evaluation by students. The approach aims to provide a comprehensive view of students’ academic performance, cognitive abilities, socio-emotional skills and creativity during class activities. HPC aligns with the National Curriculum Framework for School Education (NCFSE) to prioritise a learner-centric evaluation.

Statement 2

• HPC has been developed by Performance Assessment, Review, and Analysis of Knowledge for Holistic Development (PARAKH), a standard-setting body under the NCERT, for the foundational stage (Classes 1 and 2), preparatory stage (Classes 3 to 5), and middle stage (Classes 6 to 8), as per suggestions by the National Education Policy (NEP) 2020, marks a paradigm shift in assessing students’ overall progress.

The National Council for Educational and Research Training (NCERT) is introducing a new ‘holistic progress card’ (HPC).

Total Valid votes are = 80% of 7500= 6000
If one has 55% vote then the other has left with 45% votes
Hence, 45% of 6000= 2700

Given:

A and B together can do a piece of work in 50 days.

A is 40% less efficient than B

Concept used:

Total work = Efficiency of the workers × time taken by them

Calculation:

Let the efficiency of B be 5a

So, efficiency of A = 5a × 60%

⇒ 3a

So, total efficiency of them = 8a

Total work = 8a × 50

⇒ 400a

Now,

60% of the work = 400a × 60%

⇒ 240a

Now,

Required time = 240a/3a

⇒ 80 days

∴ A can complete 60% of the work working alone in 80 days.

Solve this question through options.
⇒  For instance, if he travelled at 25 km/h, his original speed would have been 24 km/h.
⇒ The time difference can be seen to be 6 minutes in this case = 60 / 24 – 60 / 25 = 0.1 hrs = 6 mins

Thus, 25 km/h is the correct answer. 

So Option A is correct

Relative speed = Speed of A + Speed of B = 2 + 3 = 5 rounds per hour
(∴ they walk in opposite directions)

⇒ They cross each other 5 times in 1 hour and 2 times in 1/2 hour

∵ Time duration from 8 a.m. to 9.30 a.m. = 1.5 hour

∴ They cross each other 7 times before 9.30 a.m
