Answer:

the successive discount decrease marked price distress

Answer 2

The rate of 3 rd discount is 6.25%.

Step-by-step explanation:

Since we have given that

Single discount = 19%

Successive discounts are 10%, 4% and x%.

So, when we change it into single discount becomes,

$10+4-\dfrac{10\times 4}{100}\\\\=14-0.4=13.6$

So, now, it becomes,

$13.6+x-\dfrac{13.6\times x}{100}=19\\\\x-0.136x=19-13.6\\\\0.864x=5.4\\\\x=\dfrac{5.4}{0.864}=6.25$

Hence, the rate of 3 rd discount is 6.25%.
