• i) 1 st mobile was sold out 9900 ,which means 10% gain,approximately we consider original price of the 1 st mobile is 9000.
  9000->10%gain=900=>9000+900=9900.
  ii)2nd mobile 10% loss,consider price of the second mobile 11000.
  11000->10%loss=1100=>11000-1100=9900.
  Total original price of two mobiles is =9000+11000=20000
  sold price of two mobiles is =9900+9900=19800
  difference is =200 loss
  200/20000 =1/100=>1%loss
  Ans: Loss 1%
