A single discount equivalent to three successive discounts of 10%, 12% and 15% is:

  1. A
    32.68%
  2. B
    33.55%
  3. C
    30.87%
  4. D
    31.87%

Solution & Step-by-step Explanation

Let the initial price be 100.
After 10% discount: 100×0.90=90

After 12% discount: 90×(1−0.12)=90×0.88=79.2

After 15% discount: 79.2×(1−0.15)=79.2×0.85=67.32

Total effective discount = 100−67.32=32.68%
