Percentage

Percent=Per cent=1/100


            %=1/100 

            100%==1/1    => 100*1/100=1
            50%==1/2    =>50*1/100=1/2
            33.33%==1/3
            25%==1/4
            20%==1/5
            16.66==1/6
            14.28==1/7
            12.5%==1/8
            11.11%==1/9                
            10%==1/10
            

    

           if the price of something increase with 33.33%  which is equivalent 1/3 its means the previous value of thing is 100% and after increasing it is 133.33%

            133.33%=100%+33.33%
            133.33%=1+1/3            (100%==1,  33.33%==1/3)
                           =4/3  
 if the price of something decrease with 33.33%  which is equivalent 1/3 its means the previous value of thing is 100% and after decreasing it is 66.66%

            66.66%=100%33.33%
            66.66%=1-1/3            (100%==1,  33.33%==1/3)
                           =2/3            

     Example 1-the value of table is increased with the 14.28% and the previous value of table is 1400.
            
            14.28==1/7
            previous value is 1/1 time now after increasing 1/7 times is equal to the 8/7 time
            
                            1+1/7=8/7
             ans=(8/7)*1400=1600.

 Example 2-the value of table is increased with the 25% and the previous value of table is 1000.
            
            now price times is 1+1/4=5/4
            (5/4)*1000=1250.

Example 3-the value of table is decrease with the 12.50% and the previous value of table is 2400.
           .
            now price times is 1-1/8=7/8
            (7/8)*2400=2100.
Example 4-After an Increment  of 16.66% in the cost of machine ,it becomes rs 4900 .find the initial cost of machine?
            
            now after increasing the price 7/6 times is equal to the 4900
                  7/6 ratio =4900
                   1 ratio =4200.

H.C.F From Easyway

Highest Common Factor (H.C.F):-   The H.C.F of two or more than two number is the greatest that divides each of them exactly. Easy way :- Step 1 :          First find the difference of given two least no .                         now either that difference if H.C.F or its factor  is H.C.F. step 2 :          factorize that difference. step 3 :          divide given each number with those factors. Step 4 :         multiply those factor who divide all given number. Example-Find the H.C.F of 1365,1560 and 1755 .         Step 1:-   difference=  1560-   1365                                          =195            ...

HCF And LCM

H.C.F of factor=        H.C.F of numerators                                   L.C.M of denominators L.C.M of factor=       L .C.M of numerators                                   H.C.F of denominators Note:- Multiplication   of any two number is always equal two the multiplication of its HCF and LCM .\   **           first number*second number=HCF*LCM                              eq-1 we know HCF convert numbers in ratio with divide. for Example we have two number "15 and 28" and the HCF of these numbers is 3. if we divide numbers with HCF then we find ratio 5:7 Now if the given number is in ratio of a:b then...
