Question

18. If the marked price of an article was 8400 and sold
for 6426 after offering two discounts one after the
other, the first being 15%, then the second discount
was
(1) 30%
(2) 20%
(3) 10%
(4) 12%​

Answer 1

Answer:

Step-by-step explanation:

mark price is = 8400;

Applying the first discount 15%;

Price after first discount = 8400 - (8400*15)/100

= 8400-1260 = 7140;

Let suppose second discount is X %;

So price after second discount is given as 6426 which is equal to;

6426 = 7140 - (7140*X)/100;

6426 = 7140 - 71.4X;

now finding the value of X;

We get

71.4X = 7140-6426 = 714;

71.4X = 714;

X = 10% Second discount

OPtion (3) is right

Answer 2

Answer:

10%

Step-by-step explanation:

make price is 8400

applying the first discount 15%

price after first discount =8400-(8400*15)/100

=8400-1260

=7140

let second discount is x%

so price the second discount is

6426 which is equal to

6426=7140-(7140*x)/100

6426=7140 -71.4x

71.4x= 7140-6426

71.4x= 714

x=714/71.4

x =10%
