Question

The list price of an article is Rs.800 and is available at a discount of 15 percent. Find :
(i) selling price of the article ;
(ii) cost price of the article, if a profit of `13 1/3` % is made on selling it.

Answer 1

A list price of the article = Rs.800

Discount @ 15% =`15/100xx"Rs."800`

= Rs.120

(i) S.P. of the article = Rs.800 − Rs.120

= Rs.680

(ii) S.P. of the article = Rs.680

Profit =`13 1/3%=40/3%`

C.P. =`100/(100+"Profit")xx"S.P."`

`=100/(100+40/3)xx"Rs."680`

`=100/(340/3)xx"Rs."680`

`=3/340xx100xx680` =3 × 100 × 2 Rs.

= Rs.600
