1)  

 The price of a house is decreased from 105138 to 61697 .Find the percentage of decrease.

Answer: 41%


SOLUTION 1 :

Decrease in percentage = 105138 -61697

                                       =  43441

Percentage of decrease = (43441÷105138) x 100

                                       =  0.41318077193783 x100
