Question

8. Find a single discount equivalent to two successive discounts of 20% and 10%.​

Answer 1

Answer:

28%

Step-by-step explanation:

for getting a single discount,

multiply 100 by 0.8 (for 20% discount) and then by 0.9 ( for 10% discount).

you will get 100*0.8*0.9 =72

now subtract 72 from 100

we get 28%

this is the single effective discount.
