other, the first being 15%, then the second discount was​

Answer 1

Answer:

91.36%

Step-by-step explanation:

price afterfirst discount=78400*(15/100)

=66640

Let the second discount be x.

Then, second discounted price=66640*(x/100)

As price after second discount is 6426.

So, 6426=66640-66640*(x/100)

=>6426=66640{1-(x/100)}

=>642600=66640(100-x)

=>64260=6664(100-x)

=>64260/6664=100-x

=>9.64=100-x

=>x =100-9.64

=>x=91.36%
