Question

A dealer allows his customers 20% discount on the marked price of the goods and still gets a profit of 29% What is the C.P. of goods for him marked at 1,000?​

Answer 1

Answer:

MP = 1000

SP = 1000-20% of 1000= 800

let cp= x

then x+0.29x = 800

x = 800/1.29 = 620.16 rs

Answer 2

Step-by-step explanation:

Given:-- Marked price =1000

discount =20 %

profit =20 %

find:-- cost price

Solution :

$\[ \begin{array}{l} \tt 1000 \times \dfrac{(100-20)}{100}=C.P. \times \dfrac{100+20}{100} \\ \\ \tt 1000 \times \dfrac{80}{100}=C.P. \times \dfrac{120}{100} \\ \\ \tt C.P.=\dfrac{1000 \times \cancel{80} {}^{ {}^{ {}^{ \cancel{40 }\times 2} } } \times \cancel{ 100}}{ \cancel{100 }\times \cancel{120} _{_{_{ \cancel{40} \times 5}}} } \\ \\ = \dfrac{1000 \times 2}{5} \\ \\ =400 \end{array} \]$
