• let x kg is sold at 7% profit
  so (100-x)kg is sold at 17% profit
  so the equation is formed as
  (x*7/100)+{(100-x)*17/100}=100*10/100
  => x=70
  so 100-x=100-70=30 kg is sold at 17% profit.

• let x kg of sugar is sold at profit of 7%
  then 100-x kg of sugar is sold at profit of 17%
  then according to given condition
  =>7% profit on x + 17% profit on 100-x = 10% profit 100 kg sugar
  => 1.07x + 1.17(100-x)= 1.1*100
  => 1.07x + 117 - 1.17x = 110
  => 0.1 x = 7
  => x=70
  therefore 100-x = 100-70
  => 30 kg of sugar is sold at 17% profit
