5) 65%

• If we consider 30% of profit in 1000gms it gives 1300.
  Total gms stole by dealer=500.
  gain%=500/800*100=62.5%

• Answer is 62.5% (option 2)
  Consider that he bought goods at the rate of 100rs per kg.(i.e)1000grams=100rs......eq(1)
  Now,to gain 30% profit he has to sell 1000grams=130rs.
  But he sells 800grams=130rs.
  Actual rate of 800grams=80rs..(from eq(1))
  profit %=(increased value/actual value)*100%
  here increased value=(130-80)=50
  now profit=(50/80)*100%=62.5%.

• ans:62.5%
  Let the cost price be Rs.100 for 1000gms ==>Rs.0.1 for 1grm
  Now,the selling price is 130% of 100==> Rs.130 for 800gms ==>Rs.13/80 for 1grm
  so profit%==(S.P for 1gm-C.P for 1 grm)/C.P for 1 grm *100
  By solving,We get profit%=62.5
