a dishonest grocer sells rice at a profit of 10% and also uses weights which are 20% less than the marked weight.the total gain earned by him is how much?

• lets,assume sp=110 cp=100 & we get 1kg amount with fair weights
  so, with unfair weights we will get .8kg
  for .8 kg sp110
  so for 1kg sp=110/.8-=137.5
  so,net profit=137.5-100 = 37.5%

• Let us consider a packet of rice marked 1 kg.
  
  Its actual weight is 80% of 1000 gm = 800 gm.
  
  Let C.P. of each gm be Re. 1.
  
  Then, C.R of this packet = Rs. 800.
  
  S.P. of this packet = 110% of C.P. of 1 kg = Rs.(110/100∗1000)
  
  = Rs. 1100.
  
  ∴ Gain% = (300800∗100)%
  = 37.5%.

• let 1000gm=1000rupees- equation 1
  dishonest seller use 20% less and sell 10% profit
  800gm=1100ruppes-equation -2
  make equalisiation on left side
  means
  1000gm=1000*800
  800gm=1100*1000
  profit %=(error/actual price)*100=> (300*1000/800*1000)*100=>300/8=37.5%
