What will be a single discount equivalent to a series of discounts of 10 percent, 20 percent and 30 percent?
A50.40 percent
B49.6 percent ✓ Correct
C20 percent
D45 percent
Correct answer: (B) 49.6 percent
Explanation
The single equivalent discount is 49.6%.
Remaining fractions after the discounts: 0.9, 0.8, 0.7.
Combined remaining = 0.9 * 0.8 * 0.7.
0.9 * 0.8 * 0.7 = 0.504.
Single discount = 1 - 0.504 = 0.496 = 49.6%.
