Question

find a single discount equivalent to two successive discount of 20%and 10%​

Answer 1

Original = 100

20% reduction of 100 = 80

10% reduction of 80 = 72

100-72=28

28/100=0.28

0.28*100=28%

28% discount

Answer 2

Answer:

28%

Step-by-step explanation:

=100×100-20/100×100-10/100

=100×80/100×90/100

=72%

=100-72

=28%

so single discount will be 28%
