Detailed Solution for SSC CGL Tier 1 Practice Test - 20 - Question 40

Sedimentary rocks are types of rock that are formed by the deposition of material at the Earth's surface and within bodies of water. Sedimentary rocks have also been found on Mars. Sedimentation is the collective name for processes that cause mineral and/or organic particles (detritus) to settle and accumulate or minerals to precipitate from a solution. Particles that form a sedimentary rock by accumulating are called sediment. Before being deposited, sediment was formed by weathering anderosion in a source area, and then transported to the place of deposition by water, wind, ice, mass movement or glaciers, which are called agents of denudation.

SSC CGL Tier 1 Practice Test - 20 - Question 41

The distribution of electrons into different orbits of an atom as suggested by Bohr is

Detailed Solution for SSC CGL Tier 1 Practice Test - 20 - Question 41

The distribution of electrons into different orbits of an atom was suggested by Bohr and Bury. 
The following rules are followed for writing the number of electrons in different energy levels or shells: 
i. The maximum number of electrons present in a shell is given by the formula 2n2, where ‘n’ is the orbit number or energy level index, 1,2,3,…. Hence the maximum number of electrons in different shells are as follows: first orbit or K-shell will be = 2 × 12 = 2, second orbit or L-shell will be = 2 × 22 = 8, third orbit or M-shell will be = 2 × 32 = 18, fourth orbit or N-shell will be = 2 × 42= 32, and so on. 
ii. The maximum number of electrons that can be accommodated in the outermost orbit is 8. 
iii. Electrons are not accommodated in a given shell, unless the inner shells are filled. That is, the shells are filled in a step-wise manner. 

SSC CGL Tier 1 Practice Test - 20 - Question 42

The form of carbon known as graphite

Detailed Solution for SSC CGL Tier 1 Practice Test - 20 - Question 42

· In graphite the C atoms are located in a series of stacked molecular sheets, very planar system, and each C atom positioned at the vertices of hexagons. 
· Each carbon atom takes part in 3 hexagons at the same time, and their bonding electrons are extremely delocalized through a pi-electronic system. 
· Besides, the electronic pi system is actually even more delocalized, and participates in pi-bonding of many other hexagons spread throughout the planar sheet. 
· This geometry makes graphite a great lubricant (the sheets move easily w.r.t. each other) and the in–plane electric conductivity is quite high due to the electronic delocalization. The out of plane (perpendicular) conductivity is not very high, but chemical modifications and “doping” have considerably improved this out-of-plane electrical conductivity.

SSC CGL Tier 1 Practice Test - 20 - Question 50

Newton’s laws of motion do not hold good for objects

Detailed Solution for SSC CGL Tier 1 Practice Test - 20 - Question 50

· There are two things in our universe, one- matter, second- energy. Newton's laws of motion are for matters, which occupy some space and have some mass.
Now coming to query, First of all it is not possible for any matter to travel with spped of light or even close to it. For this, there is hypothesis given by Einstein on relativity. As per him, every object have two masses, one rest mass and second mass in motion.
He developed a formula relating both mass and energy, which is termed as energy mass equivalence. E=mc2
· as speed of object approaches speed of light, mass tends to increase. And at speed of light, it becomes infinite. When the object is already traveling near the speed of light, it cannot move much faster, no matter how much energy it absorbs. Its momentum and energy continue to increase without bounds, whereas its speed approaches a constant value—the speed of light. This implies that in relativity the momentum of an object cannot be a constant times the velocity nor can the kinetic energy be a constant times the square of the velocity. Thus new dimension to Newton's law came into light, in which F=ma is not directly applicable, as here m is considered as rest mass not relativistic mass.
So, simple laws of morion provided by newton will not hold perfect to object moving at higher speed near to speed of light !

SSC CGL Tier 1 Practice Test - 20 - Question 54

A shopkeeper buys an article for Rs. 360. He wants to make a gain of 25% on it after a discount of 10%. The marked price is …

Detailed Solution for SSC CGL Tier 1 Practice Test - 20 - Question 54

shopkeeper buys an article in Rs 360 
Discount = 10% 
Profit = 25% 
Let market price = X 
Discount = X/ 10 
After discount price = X- X/10 = 9X/10 
Profit = 9X/10 – 360 
% profit = 25% of 360 = 25×360/ 100 = 90 
Hence 9X/10 – 360 = 90 
9X/ 10 = 450 
X = 500 
Hence market price = Rs. 500

SSC CGL Tier 1 Practice Test - 20 - Question 57

A can do a piece of work in 4 days while B alone can do it in 6 days. With the help of C, they can complete the work in 2 days. If they are paid Rs.1440 for the whole work, how much money A gets?

Detailed Solution for SSC CGL Tier 1 Practice Test - 20 - Question 57

et the total work be 12 units. 
Work done by A in one day = 12/4 = 3 units 
Work done by B in one day = 12/6 = 2 units 
Work done by A in 2 days = 6 units 
Work done by B in 2 days = 4 units 
Work done by C in 2 days = 12 – 6 – 4 = 2 units 
A’s share from the total money = 720

SSC CGL Tier 1 Practice Test - 20 - Question 58

Ten years ago the average age of a family of four members was 28 years. Two children having been born, the present average of the family is the same. What are the present ages of the children if the age difference between both the children is 2 years?

Detailed Solution for SSC CGL Tier 1 Practice Test - 20 - Question 58

en years ago, age of 4 members 
28 × 4 = 112 years
