What is unitary method with example

Unitary Method: 
This is the method of carrying out a calculation to find the value of a number of items by first finding the cost of one of them. It is a technique in Mathematics to solve particular types of problems. Unit means one,in this method, we first find the value of one. To find the value of one ,. When we have the value of many ,we divid:   Steps: (i)Find the value of one unit.   (ii) Find the value of required units .                                     Example  No1: 5 pencils cost Rs 15 .how much does 1 pencil cost?                                      Solution:.         Cost of 5 pencils= Rs 15                                            Cost of 1 pencils= 15/5 = Rs . 3.                 Example No.2.  5 buses carry 300 passengers .How many passengers can 9 buses Carry?                                                            Solution: 5 buses carry passenger= 300.                             1 bus carries passenger=300/5= 60.                 9 bus carry passengers= 60×9= 540.                                                                                                   Example No 3.  I got 686 marks out of 850 marks .what is the percentage of may marks?                                                                Solution: Marks out of 850 = 686.                                         Marks out of 1 = 686/850.                                   Marks out of 100= 686/850×100%=80.7%.                                                                                                                               Example No 4. 5 workers can complete a work in 20 days. In how many days same work will be completed if 10 workers are employed ?                                                                         Solution: 5 workers complete the work in days= 20 days.                                             1 worker complete the work in days= 20×5  10 workers complete work in days= 20×5/10= 10 days.                                                                                  Activity.       (   A ) if the price of 12 radios is Rs .3780 .Find the price of 30 such radios.                                                                        Solution: 12 radios price = 3780.                          Find the price  30 radios= 3780× 30 = 113,400.                                                                       So 30 radios price    113,400                              (B) if price of one dozen eggs is Rs. 108,than what will be the price of 200 eggs?                                                                              Solution: one dozen price= 108                                          The price of   200 eggs    200× 108=21,600.                                                                So price of 200 eggs = 21,600.                              ( C) Price of 15 m cloth is Rs 1050.50 .what will be the price of 22 m of the cloth?            Solution ;                                                                  price of 15 m cloth= 1050.50.                              The price of 22 m cloth = 1050.50× 22= 22,275.                 So 22 m cloth price = 22,275.                                                                                              percentages And unitary method.                 Percentage means per 100 i.e.50%=50/100.         Percent= 1/100.                   Percentage can be expressed as a decimal or a fraction.        In unitary method, first we find out the cost of one item, then we can find out the cost of a number of items.              The unitary method is a technique in elementary algebra for solving a class or problems in variation. It consist of finding one of the variables to a single unit i.e.1, and then performing the operation necessary to alter it to the desired value.

What is Arithmetic and percentages

  Q1 . Define percentage. When a number is expressed as a fraction of 100 i.e, per 100 it is called percentage . The word percentage  is derived from the Latin word per centum mean out of hundred. It's symbol is % .For example , 72% ( read as  seventy two percent)  =72/100,50%,50/100,100%=100/100.      Activity No 1: A . Express the following percentages, as fraction in the lowest from .    (I) 72%.   (II) 92%.  (III) 15%.  (IV) 2 1/2%              I) 72 %.                Solution : 72%= 72×1/100=72/100=36/50=18/25                              Ii) 92%              solution ; 92%= 92×1/100=92/100=46/50=23/25.                             III) 15%.      ...

3 types of heat transfer Definition

  Transfer of Heat:.   If you have experience the campfire while camping, you have noticed that the heat is transferred from the campfire to you and you feel warm glow on your face. If an iron utensil is placed on the fire, it becomes hot. Even someone far away of about 20 feet,also feel the warmth of the fire. In each of these cases the transfer of heat from fire to the iron utensil ,to your face and the person 20 feet away has occurred.But the principle method of heat transfer involved in each was different . The heat transfer is relating to two things ,one is the temperature ,and the other is the flow of heat. Temperature represents the amount of thermal energy available, whereas heat flow represents the movement of thermal energy from place to place. There are three basic methods to transfer the heat, conduction,convection and radiation.                Conduction:. Heat travelled from the end of the iron untensil to the handle p...
