RRB ALP & Technician Mock Test (English) - 24 - Railways MCQ

Some important points about Isometric Drawing:

• It is a type of pictorial projection in which all three dimensions of an object are shown in one view and if required, the actual sizes can be measured directly from it.
• The perpendicular edges of an object are drawn on 3 axes at 120° to each other.
• All lines parallel to the isometric axes in an isometric drawing are called isometric lines. Non-isometric lines are not parallel to any of the isometric axes. Measurement can be made only on the isometric lines and axes.

There are three types of axonometric projections:

Trimetric projection: All the three axes of space appear unequally foreshortened. None of the angles are equal.

Dimetric projection: Two of the three axes of space appear equally shortened. Two angles are equal.

Isometric projection: All the three axes of space appear equally foreshortened. All three angles are equal.

Which of the following are components of Central Processing Unit (CPU)?

• Arithmetic logic unit and Mouse

• Arithmetic logic unit and Control unit

  54% answered correctly

• Arithmetic logic unit and Integrated Circuits

• Control Unit and Monitor

Central Processing Unit (CPU): It is the most important unit, where all the processing jobs take place. CPU is the control centre of the computer and hence it is said to be the brain of the computer. CPU has three main components:

1. Arithmetic Logic Unit (ALU): It performs all the arithmetic operations like addition (+), multiplication (*), subtraction (-), division (/) on the numerical data directed by the control unit. All the logical operations, like less than (<), greater than (>), equal to (=), not equal to (≠) etc. are also carried out by ALU.
2. Control Unit (CU): It controls and coordinates all the operations taking place in the system. It controls the flow of data and information from one unit to the other.
3. Registers/Memory Unit (MU): To execute a program, data and instructions need to be stored temporarily. This storage is done in the MU. The data and instructions are retrieved from MU by Control Unit for supplying to ALU as when required by the program.

We know that one to the power of any number will always be one

Units digit in (4211)¹⁰² = 1

Units digit in (361)⁵² = 1

∴ Units digit in (4211)¹⁰² × (361)⁵² is also 1

It is true that nothing is for free but a life is worth more than any amount of money and money comes and goes but a person once dead cannot be brought back to life. So doctors/authorities who do not treat critical patients just because of insufficient money should be put on trial. Hence only argument II is strong and option 2 is correct.

As Mumbai is the biggest city of India similarly London is the biggest city of Britain.

Ecology is the study of how organisms interact with one another and with their physical environment of matter and energy. It is the reciprocal relation between living and non-living components (like their environment).

An ecosystem is a place, such as a rotting log, a forest, or even a schoolyard, where interactions between living and non-living things occur.

The given table:

The given conditions in tabular form:

 

Let’s first convert the word as per the code table:

BERPSAIM → 01639427. It is still not complete as we have to check for the given conditions.

Here, 1^st and 3^rd rule applies, since 3 vowels are present while consonants are present on extreme ends. So, A, I & E will be replaced as 8 each. Besides, code for B & M on extreme will be replaced by ? each. Hence, BERPSAIM becomes ?863988?

Hence, ?863988? is the answer.

The given table:

The given conditions in tabular form:

 

Let’s first convert the word as per the code table:

BIPSA → 02394

By checking the conditions, we see that no rule apply for this word; hence the answer will be 02394.

Hence, 02394 is the answer.

The given table:

The given conditions in tabular form:

 

Let’s first convert the word as per the code table:

AIRE → 4261. It is still not complete as we have to check for the given conditions.

Here, 1^st and 2^nd rule applies, since 3 vowels are present while only 1 consonant is present. So, all the vowels should be coded as 8 and consonants should be coded as -; hence, AIRE will be coded as 88-8.

Hence, 88-8 is the answer.

The number are repeated as many times as their face value.

So, 12333 4444 55555 666666 is the complete series.

Hence, 346 will complete the series.

Philippines President Rodrigo Duterte has announced the ​immediate withdrawal of Philippines from the International Criminal Court. This comes after ICC started an investigation into allegations of crimes against humanity committed by Duterte in his war against drugs. He has accused U.N. special rapporteurs & ICC investigators of painting him as a "ruthless and heartless violator of human rights.

B got more marks than C → B > C

D got more marks than E but less marks than A → A > D > E

We will try to arrange the given information ⇒ B > C, A > D > E

Now it is told that B got more marks than two students it means B got 3rd position and also everybody scored more marks than F it means F got last position.

So if now will arrange then we will get the following order,

B > C > F

And it is told that A > D > E

So only one possible way is there that is, A > D > E > B > C > F

Therefore, D got the 2^nd highest marks.

Work is the product of net force and displacement, so the area under a ‘force vs. displacement graph’ is the work done by the force.

W = A_OBC + A_BCD + A_DEF

The pattern of series is:

(D × B → 4 × 2 = 8), (J × A → 10 × 1 = 10), (B × G → 2 × 7 = 14), (E × C → 5 × 3 = 15), (H × B → 8 × 2 = 16)

Thus, instead of JA9 it should be JA10.

Here, each number except 38 is prime number + 3

73 + 3 = 76,

41 + 3 = 44,

53 + 3 = 56,

35 + 3 = 38

But 38 is not a prime number, thus 38 is the odd number.

The ministries of agriculture and skill development signed an agreement to conduct training programmes for agriculture and allied sectors at 690 Krishi Vigyan Kendras. The aim is to intensify the pace of skill development in 690 Krishi Vikas Kendras country-wide by training an agricultural workforce. Radha Mohan Singh is Agriculture Minister.

Relative density of a body is defined as the ratio between the densities of the body to the density of water at 4°C (1 g/cm³or 1000 kg/m³).

Unit: Since the relative density is a ratio of two densities, it has no unit.

1) Ravi walks in the west direction for a distance of 4 km.

2) He then turns southwards and walks for 3 km. He then turns towards east and walks for 8 km.
 

Applying Pythagoras’s Theorem, we get the required distance as 5 km.

For the first time in the nation's history, Saudi Arabia's women participated in an all-female marathon. The three-km-long marathon, held in the eastern province of al-Ahsa on Saturday, reportedly saw participation from 1,500 women across several categories. Earlier in January, Saudi Arabia allowed its women, for the first time, to spectate at a football match.

Vladimir Putin will lead Russia for another six years, after securing victory in the presidential elections held on 18th March. Putin, who has ruled Russia for almost two decades, won more than 75% of the vote. He was well ahead of his nearest rival Communist Party candidate Pavel Grudinin.

a² – b² = (a + b)(a – b)

Given, x = √3 + √2

∴ 1/x = 1/(√3 + √2)

Multiplying and dividing by √3 - √2

An accident is an unplanned or undesirable and non - controlled event that brings loss or injury.

Accidents are primarily a result of an unsafe act and/or an unsafe condition.

Mass of the jar with water = Mass of the empty jar + Mass of the water filled = 1090 g

Mass of the empty jar = 305 g

Mass of the water filled = 1090 – 300 = 790 g

As android is launched by Google similarly windows is launched by Nokia.

Total number of balls = (5 + 4 + 11) = 20 balls

S = Sample space that one ball is drawn out of the box

∴ n(S) = 20

Let E = event that the ball drawn is neither black nor pink = event that the ball drawn is yellow

Thus, n(E) = 4

∴ Probability of occurrence of event;

Arunachal Pradesh Assembly passed a bill to remove Anchal Samiti, intermediate level of the three-tier Panchayati Raj system, and set up a two-tier system in the state. In a two-tier system, the strength of elected members would be reduced. In a two-tier system, planning and execution of schemes would be faster as there would be a direct connection between Gram Panchayats and Zilla Parishad.
