Answer:

C. 1600

Read Explanation:

The total number of candidates who appeared for the exam is 1600.

Step-by-Step Calculation

  1. Find the failure percentage:

    • Total candidates = 100%100\%

    • Passed candidates = 86%86\%

    • Failed candidates = 100%86%=14%100\% - 86\% = \mathbf{14\%}

  2. Set up the equation:

    • We are given that 14%14\% of the total candidates equals 224224.

    • Let the total number of candidates be xx.
      14100×x=224\frac{14}{100} \times x = 224

  3. Solve for xx:
    x=224×10014x = \frac{224 \times 100}{14}

  4. x=16×100=1600x = 16 \times 100 = \mathbf{1600}
