Question

Find the singal discount equivalent to two successive discount of 15% and 20%

Answer 1

32 percent

Let the amount be 10.

1st Dscount = 15% × 10 = 1.5

Amount Remaining = 8.5

2nd Discount = 20% × 8.5 = 1.7

Amount Remaining = 6.8

Total Discount = 1.5 + 1.7 = 3.2

Discount% = (3.2 / 10) × 100 = 32%
