If the selling price of 16 cows is equal to the cost price of 20 cows, then find?

If the selling price of 16 cows is equal to the cost price of 20 cows, then find?

If the selling price of 16 cows is equal to the cost price of 20 cows, then find?

If the selling price of 16 cows is equal to the cost price of 20 cows, then find the gain or loss percentage. This question is asked in mock test of SSC CGL, CHSL competition exam. 

Another method of asking this question in everywhere is If the selling price of 16 items is the same as the cost price of 20 items, then there is a loss or gain.

Solution :- 

Lets Suppose the Selling price of 1 cow or item is Rs. 1

Then the Selling price of 16 Cows or items = Rs. 16.

Hence, as given in the question that,

The cost price of 20 cows or items is equal to the selling price of 20 cows or items.

that means,

CP of 20 cows = Rs. 16

CP of 1 cow = 16 / 20 = 4 / 5

= Rs. 4/5 = Rs. 0.8

Now, profit percent on each cow = profit / CP x 100

profit % = SP of each cow - CP of each cow / CP x 100

Profit % = (1 - 4/5 = 1 / 5 = Rs. 0.2) 0.8 /  x 100

=  0.2 / 0.8 x 100

= 2/8 x 100

= 25%

One More Example to illustrate the answer.

Q. The Cost price of 25 toys is equal to the selling price of 20 toys. find gain or loss percent.

Lets Suppose the cost price of 1 toy or item is Rs. 1

Then the cost price of 25 toy = Rs. 25.

Hence, as given in the question that,

The cost price of 25 toys is equal to the selling price of 20 toys.

that means,

SP of 20 toys = Rs. 25

SP  of 1 toy = 25/20 = 5/4 = 1.25

gain = SP  - CP = 1.25 - 1.00 = .25

Gain % = .25 / 1  x 100 = 25 %
How to calculate CGPA in Engineering VTU - vtu CGPA calculation

How to calculate CGPA in Engineering VTU - vtu CGPA calculation

How to calculate CGPA in Engineering VTU - vtu CGPA calculation

CGPA means Cumulative Grade Points Average. CGPA is commonly used in CBSE board but now, it is also use in many engineering college to measure your semester marks. here in this particular post we will learn how to calculate cgpa in engineering vtu.

How to Calculate cgpa in engineering vtu

Given below are the same rules on ow to calculate CGPA in Engineering vtu. Engineering vtu is an another method of calculating CGPA in your engineering college.

Even if is not wrong if we say VTU CGPA calculation is one of the finest and easiest way to calculate CGPA in your engineering college.

Here are the quick formula and easy rules to calculate VTU CGPA.

VTU CGPA = (Your aggregate percentage / 10) + 0.75.

Lets Suppose your aggregate percentage is 80. Then your VTU CGPA will be,

VTU CGPA Calculation = 80 / 10 + 0.75

= 8 + 0.75 = 8.75

Required vtu CGPA = 8.75

What is VTU CGPA?

The mathematical definition of VTU cgpa is VTU CGPA = ∑(Ci x Si) / ∑ Ci.

Where, 'si' is less than the SGPA and 'ci' is less than total credit in a particular semester.

In other words, VTU CGPA is defined as, It is equal to the sum of your aggregate percentage and 0.75.

As you can see in the above examples of VTU CGPA calculation the required VTA CGPA calculation is 8.75.
What is Unit and Measurement in Physics - Easy language

What is Unit and Measurement in Physics - Easy language

What is Unit and Measurement in Physics - Easy language

In this post we will discuss about the very first topic of physics unit and measurement. means the starting phase of physics. If you to the even big universities, your physics professor start your first class with this topic i.e, unit and measurement. So, you can imagine how important this chapter is.

So, if you are a physics student then you must have to know these two topics. first is unit and second is Measurement because this is the base of the physics.

Unit and Measurement Introduction:- 

Physics:-  The study of nature and natural things.

  • It is the made of greek word " Fusis" means natural things and nature.
  • It means that physics is the study of nature and its laws.
  • Physics is the foundation of engineering and technology.
  • Physics is based in experiment when experiments are done then it measure with the help of physical quantity.
  • Quantity means it represents the number.

Physical quantity:- It is represent of the physical laws in the term id quantity.

  • It is of two types
  • Scalar quantity and vector quantity.
  • Scalar quantity means it has only magnitude not direction.
  • vector quantity means it has both magnitude and as well as direction.


What is Unit?

A unit is defined as the single word or a symbol that supports a physical and derived quantity. On other words, A unit is defined as a single things of a group of things. like a building of 10 rooms is expressed in unit as single room. 

In other words, a 2 meter wide and 5 meter high wall has a unit of one bricks. In Physics Unit has its own identity. means without unit we cannot define the magnitude of acceleration, velocity, motion, etc.

It is of two types

  • Fundamental unit
  • Derived unit

1.     Fundamental unit:- It is not depend another unit, three fundamental unit are mass, length and Time.

2.     Derived unit:- It is depend in fundamental unit.

system of unit are four types

1.     Mks system:- In this system Length, Mass and Time are expressed in meter, Kilogram, and Second.

2.     Fps system:- In this system Length, Mass and Time is expressed in Foot, Pound, second.

3.     CGs system:- In this system Length, Mass and Time is expressed in Centimeter, Gram, second.

4.     S.I system;- ( international System of Unit )  In S.I system having seven fundamental unit.

 

Some examples of physical quantities with their si units and cgs units

Here is a collection of 5 fundamental and derived physical quantities which commonly used in physics with their si units and CGS units. Also describe the derived quantity with derivation.

We have already discussed about the definition of physical quantity in the above definition. But lets define the physical quantity in another words.

Physical quantity are those quantities which represents the quantities of any material with the help of some symbols attached with numerical values. For example a container contains 6 kilograms of wheat. So we can write 6 kg. Here kg is the physical quantity attached with numerical value of 6.

As we have already seen above that, Physical quantities are two types first is fundamental quantity and second is derived quantity. These are the following 5 physical quantities (both fundamental and derived) with their si units and CGS units. Before we start discussing following 5 physical quantities. Please note that some quantities are derived from fundamental quantity.


  1. Mass
  2. length
  3. Time
  4. Acceleration
  5. Velocity

What is measurement?

Measurement is defined as, it is a fixed number or quantity of any substance, objects, or things that depends on a definite universal or a particular objects.

For example, lets suppose we have to measure our body temperature. So, we use thermometer because thermometer is a universal or a particular object that the whole world use for measuring temperature in 


How Rest and motion are related to each other - Relation with example

How Rest and motion are related to each other - Relation with example

How Rest and motion are related to each other - Relation with example

If you follow this science laws journey with me from past some years. Then you must be aware of Physics chapter i.e, Motion. In Motion we have already studied a lot abut motion and moving things or objects. But apart from the motion in motion chapter, there is also a concept of Rest.

So, here we will discuss not only rest and motion but also how they both related to each other. we will try to understand it with the help of two most common and easily understandable examples. So lets get started.

Motion,

In physics a things which can see, touch and feel is called object or body. It is the branch of physics which deals with the study of the object at rest and in motion. Object in rest A body is said to be rest if it does not change its position with respect to its surrounding with the passage of time. Object in motion If the position of the body changes its state with respect to its surrounding then body is called in motion.

Rest and motion are relative terms

Rest and motion are relative terms because object can be at rest with respect to one things and in motion with respect to some other things at the same time, so motion is not absolute, it is relative. for example---
  • Suppose you are sitting in a train which is moving then we are at rest with respect to the other passenger sitting in that compartment but in motion with respect to the objects on the ground.
  • Our house is at rest with respect to the other house on the earth but it is in motion with respect to an observer on the moon.

Types of motion

One dimension, two dimension motion, three dimension motion.

One dimension motion:- 
  • The motion in a straight lines is called one - dimension motion.
  • Moving of bus in a straight line.
  • Falling of an apple from tree.
  • If only co - ordinate is used from three co - ordinate x, y and z then the motion is one dimension motion.
Two dimension motion;-
  • Motion in a plane is called two dimension motion.
  • If only two co - ordinate is used from three co - ordinate x, y and z then it is called two dimension.
  • The motion of object in horizontal and vertical circle.
  • The earth revolving around the sun.
  • S carom coin in motion.
Three dimension motion;-
  • Motion in space is called three dimension motion.
  • If all co - ordinate is used then it is called three dimension motion.

Position:-
  • If particles on the origin then its position will be zero.
  • If particles move along the positive direction of x - axis then its position positive.
  • If particles moves along the negative direction of x - axis then position negative.
