DIVIDE THE QUANTITY BY FRACTION OBTAINED FROM PERCENTAGE 

If we would like to calculate a quantity from a given percentage of the quantity, then we have to express the given percentage as a fraction and divide the quantity by the fraction.

 

1)  If 75 % of a number is 150, then find the whole number

Ans.)  as per the given condition  75 % of a number is 150

 Then 100 % or full number would be =  150 ÷ 75/100

                                 100

               =  150  X  -----------  =  200        (Ans.)

                                 75

 

2)  If 25 % of a number is 40, then find the whole number

Ans.)  as per the given condition  25 % of a number is  40

 Then 25 % or full number would be =  40 ÷ 25/100

                                        100

                        =  40  X  -----------  

                                         25

                        =   40 X 4  =  160          (Ans.)
