Question

Alfred buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is:

Answer 1

cost of scooter=Rs.4700
repairs cost=Rs.800
total CP=Rs.4700+800=5500
SP=Rs,5800
SP>CP, it is a gain
gain=SP-CP=Rs.(5800-5500)=Rs.300
gain%=gain/CP X 100%
300/5500 X 100%=5.45%

Answer 2

CP of old scooter = Rs.4700
Repairing cost= Rs.800
Overall CP= 4700+800
                  =Rs.5500

SP of scooter= Rs.5500
Since SP>CP there is profit

Profit=SP-CP
         =5800-5500
         =Rs.300
profit %= P/CP x 100
             = 300/5500x100
             =    5.45 %
