      A 13.33 kg Correct Answer Incorrect Answer
      B 21.82 kg Correct Answer Incorrect Answer
      C 16.25 kg Correct Answer Incorrect Answer
      D 11.12 kg Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let the quantity of sugar sold at 16% profit be β€˜x’ kg and the quantity of sugar sold at 8% profit be β€˜35 – x’ kg.

      ATQ;

      22 Γ— 0.08 Γ— (35 – x) + 22 Γ— 0.16 Γ— x = 100

      Or, 61.6 - 1.76x + 3.52x = 100

      Or, 1.76x = 38.4

      Or, x = 21.82

      Therefore, the shopkeeper sold 21.82 kg of sugar at 16% profit.
