Question

Answer 1

Ram sold two watches at rs 240 each. 
total s.p =480

he gets 20% profit on first
c.p =[s.p*100/100+20% profit]
        =[240*100/120]   
          =200

20% loss on the other
c.p =[s.p*100/100-20% loss]
        =[240*100/80]   
          =300
total c.p=200+300=500
toal s.p=480 
loss= c.p-s.p
          =500-480
           =20
loss%=[(20/500)*100]
            =4% loss
