The table given below shows the marked price and discount percentage of five different articles.

Article Marked price Discount percent

P 300 20 percent

Q 600 25 percent

R 400 16 percent

S 700 22 percent

T 800 30 percent

Selling Price = Marked Price - (\({{Marked \ Price \ × \ Discount} \over 100}\))

J1 = Total selling price of article P and R.

J2 = Total selling price of Q and T.

What is the value of (J2 - J1)?

Answer 1

Given:

Selling Price = Marked Price - (\({{Marked \ Price \ × \ Discount} \over 100}\))

J1 = Total selling price of article P and R.

J2 = Total selling price of Q and T.

Calculation:

Selling price of P =

300 - \({{300 \ × \ 20} \over 100}\)

⇒ 300 - 60

= 240

Selling price of Q is,

600 - \({{600 \ × \ 25} \over 100}\)

⇒ 600 - 150

= 450

Selling price of R is

400 - \({{400 \ × \ 16} \over 100}\)

⇒ 400 - 64

= 336

Selling Price of T

800 - \({{800 \ × \ 30} \over 100}\)

⇒ 800 - 240

= 560

So, J2 = Total selling price of Q and T.

450 + 560 = 1010

J1 = Total selling price of article P and R.

336 + 240 = 576

So, (J2 - J1) ,

1010 - 576 = 434

The value of (J2 - J1) is 434
